Common factors of 2-digit whole numbers

A factor of a given number is a number that can divide the given number without a remainder. For instance 2 can divide 6 without a remainder, hence 2 is a factor of 6.

Rules for divisibility

2: A number is divisible by 2 if the last digit is an even number or zero.

3: A number is divisible by 3 if the sum of the digits is divisible by 3. For example, 4 302.

4 + 3 + 0 + 2 = 9, this is divisible by 3. Hence 4 302 is divisible by 3. Therefore,

3 is a factor of 4 302.

4: A number is divisible by 4, if the last two digits are zeros or if the last two digits of the number is divisible by 4.

Examples

- 324 is divisible by 4 because the last two digits (24) are divisible by 4.
- 736 is divisible by 4 because the last two digits (i.e. 36) are divisible by 4. 5: A number is divisible by 5 if the last digit is either 5 or zero.

Examples

75 is divisible by 5 Hence 5 is a factor of 75

80 is divisible by 5 5 is a factor of 80

76 is not divisible by 5. 5 is not a factor of 76.

78 is divisible by 2 76 is divisible by 2

78 is also divisible by 3 but 76 is not divisible by 3.

Hence 78 is divisible by 6. (Remember 7 + 6 = 13 and 13 is not divisible by 3)

! 6 is a factor of 78. Since 2 but not 3 can divide 76 without remainder. Thus 76 is not divisible by 6.

! 6 is not a factor of 76.

7: A number is divisible by 7 if the difference between twice the last digit and the number formed by the remaining digits is divisible by 7.

Examples

- Consider 91 2. Consider 959

The last digit is 1. The last digit is 9.

Twice the last digit is 2 × 1 = 2. Twice the last digit is 2 × 9 = 18. The remaining digit is 9. The remaining digits = 95.

Difference between 9 and 2 is 7. Difference between 95 and 18 = 95 – 18 = 77

Since 7 is divisible 7. Since 77 is divisible by 7.

91 is also divisible by 7. 959 is also divisible by 7. Thus 7 is a factor of 91. Thus 7 is a factor of 959.

8: A number is divisible by 8 if the last three digits are zeros or the number is divisible by 2 without a remainder three times.

Examples

- Consider 784 2. Consider 74

784 ÷ 2 = 392 (First division) 748 ÷ 2 = 374 (First division)

392 ÷ 2 = 196 (Second division) 374 ÷ 2 = 187 (Second division)

196 ÷ 2 = 98 (Third division) 187 ÷ 2 = 93 remainder 1 (Third division)

Thus 784 ÷ 8 = 98 Here 748 cannot be divided by 2, without a remainder, three times.

Thus 8 cannot divide 748 without a remainder.

Hence 8 is factor of 784. Therefore 8 is not a factor of 748. 20

9: A number is divisible by 9, if the sum of its digits is divisible by 9. Examples

- Consider 801 2. Consider 234 8 + 0 + 1 = 9 2 + 3 + 4 = 9

Since 9 is divisible by 9 Since 9 is divisible by 9

Then 801 is divisible by 9 Then 234 is divisible by 9 Hence 9 is a factor of 801. Hence 9 is a factor of 234.

10: A number is divisible by 10 if the last digit is ZERO. For example, 180 is divisible by 10

but 108 is not. Thus 10 is a factor of 180, but not a factor of 108. How to find the factors of a given number

Starting from 1, find all other numbers that can divide the given number without a remainder.

Infant mortality: The number of deaths of babies at birth or just after birth per 1 000 live-births in the population of a place.

47

Examples

2 800 children were born in a Nigerian city with a population of 250 000. Here the birth rate is calculated. Ratio of population to number of births

800

250

11.2

Therefore, the birth rate is 11 births/1 000.

If 1 820 children were born by all the women in town numbering 910, find the fertility rate. Study this answer. Ratio of the number of women to the number of children born

=910: 1 820

1: 2

Therefore, fertility rate is 2 children/woman.

1 890 people died in a year in a town with a population of 63 000. Here the death rate is calculated. Ratio of number of people to number of deaths

=63 000: 1 890

=1 000: 1890

63

=1 000: 30

Therefore, the death rate is 30 deaths/1 000.

Exercise 4

- In a new capital city established by a government, the population was 32000. If the total number of children born that year was 672, what was the birth rate?
- If 1 845 children were born by all the women numbering 315 in a community, find the fertility rate.
- A total of 2 002 deaths were recorded in a community with a population of 154

- Calculate the death rate.

- Find the total number of deaths in a city with a population 80 000, if the death rate is 13/1 000.

Examples

The number of infant deaths recorded among 78 000 live-births in a constituency was 1 560. Here the infant mortality rate has been calculated.

The ratio of the number of live-births to the number of infant deaths

=78 000: 1 560

=1 000: 1560

78

=1 000: 20

Therefore, the infant mortality rate is 20 deaths/1 000 live-births

In a year, the death rate recorded in a village with a population of 80 000 was 12 deaths/1 000. Here the total number of deaths in that year has been calculated.

Ratio of death rate

=1 000: 12 deaths

=80 000: 12 × 80

=80 000: 960 deaths

Therefore, number of deaths =960 48

Study these statements:

The cost of 1 pencil is �10.00

Then the cost of 4 pencils is �40.00 Likewise the cost of 12 pencils is �120.00

As the number of pencils increases the cost also increases. The ratio of number of

We say, proportion is an equation showing when two ratios are equal. For example, 1/10=4/40

Since 1: 10 =4: 40

We can then say that the cost of the pencils is in direct proportion to the number of pencils.

Examples

- The cost of five pairs of shorts is �1 340. Find the cost of eight pairs. These workings show how this word problem is solved.

Solution

5 pairs of shorts cost #1 340

1 pair of shorts costs #1 340/5 [Divide N1 340 by 5]

=268

8 pairs of shorts will cost #268 ×8 [Multiply the cost of one pair by 8]

=#2 144

Direct proportion 58

- The cost of petrol is #97.00 per liter.

What is the cost of 5 liters? How many liters do I get for �1 455.00? Solution

1 liter of petrol costs #97.00

5 liters of petrol will cost #97 ×8 =485.00 #97.00 is the cost of 1 liter of petrol.

#1 455.00 will be the cost of1/97×1455/1 liters of petrol =15 liters of petrol.

- The following solutions work out costs if a kilogram of apples cost N600.00. Weight, W (kg) 0 1 2 3 4

Cost, C (Naira) 600

Solution

1 kg of apples costs =#600

3 kg of apples will cost =#600 ×3

=#1 800

- kg of apples costs -#600
- kg of apples will cost =#600 ×2

=#1 200

1 kg of apples costs =#600

4 kg of apples will cost =#600 ×4

=2 400

The table is

Weight, W (kg) 0 1 2 3 4

Cost, C (Naira) 0 600 1200 1800 2400

The cost is directly proportional to the weight of apples. Exercise

Indirect proportion Study the table below.

Number of girls to scrub 1 2 3 4 5 6

Time taken (mins) 60 30 20 145 12 10

The above table shows the number of girls that can scrub a room and the time that it will take to complete the work.

You will observe that as the number of girls increases the time taken to complete the work decreases, in the same way. The product of the number of girls that scrub and the time taken are all equal.

That is: 1×60 =2 ×30 =3 ×20 4 ×15 =5 ×12= 6 ×10.

This type of proportion is called inverse proportion or indirect proportion. Examples

If 10 girls are to scrub the room, how many minutes will it take them? Study the solution to this word problem.

Solution

Number of girls ×time taken =60

10×time taken =60

Time taken =60

10

=6 minutes

If 15 laborers can load a ship in 10 days, how many extra laborers must be employed to load the ship in 6 days? Study the solution.

Solution Method 1

Product of 15 laborers and 10 days =15 ×10 =150

Thus 6 days ×the laborers =150 The laborers =150/6=25

The extra laborers to be employed = 25 – 15 =10 60

Method 2

In 10 days, the laborers to load the ship =5

In 1 day, the laborers to load the ship will be =15 ×10

In 6 days, the laborers to load the ship will be =15× 10/6

25

Thus the extra laborers to be employed 25 – 15 =10 Examples

In 1 day the farm will be completely weeded by 12 ×6 men. (In 1 day more men would have to weed the farm)

In 8 days the farm will be completely weeded by 12× 6/8men =9 men. Exercise

Word problems Examples

Study this example to find out how the following word problem was solved:

A poultry farm produces 2 568 eggs a day. How many eggs will it produce in 28 days?

Number of eggs produced per day = 2 568

Number of eggs produce in 28 days = 2 568 ×28 eggs

= 2 5 6 8

×× 2 8

2 0 5 4 4 = 2 568 ×× 8

5 1 3 6 0 = 2 568 × ×20
