Solution

Converting factors of 17,20

Factors are numbers that can divide without remainder.

Factors of 17

17/1 = 17         gives remainder 0 and so are divisible by 1
17/17 = 1         gives remainder 0 and so are divisible by 17

Factors of 20

20/1 = 20         gives remainder 0 and so are divisible by 1
20/2 = 10         gives remainder 0 and so are divisible by 2
20/4 = 5         gives remainder 0 and so are divisible by 4
20/5 = 4         gives remainder 0 and so are divisible by 5
20/10 = 2         gives remainder 0 and so are divisible by 10
20/20 = 1         gives remainder 0 and so are divisible by 20
