Topic : Factors of Numbers (Continuation)
Factors are numbers that can divide a given number perfectly without any remainder.
Examples
1. Write out two factors
of 14
Solution
14 ÷ 1 = 14
14 ÷ 2 = 7
14 ÷ 3 = 4 R 3
14 ÷ 4 = 3
14 ÷ 5 = 2 R 4
14 ÷ 6 = 2 R 2
14 ÷ 7 = 2
14 ÷ 8 = 1 R 4
14 ÷ 9 = 1 R 5
1 4 ÷ 10 = 1 R 4
14 ÷ 11 = 1 R. 3
14 ÷ 12 = 1 R 2
14 ÷.13. =. 1.R.1
14÷ 14. =. 1
Factors of 14 are :
1, 2, 7 and 14
.. Write out two factors of 14
Answer = 2 and 7
We just want to take just two factors of 14. We can take any two factors which are 2 and 7
The factors of 14 are more than two, but we just need 2 of them we shall take just two factors which are 2 and 7
