Solution

Converting factors of 12,15

Factors are numbers that can divide without remainder.

Factors of 12

12/1 = 12         gives remainder 0 and so are divisible by 1
12/2 = 6         gives remainder 0 and so are divisible by 2
12/3 = 4         gives remainder 0 and so are divisible by 3
12/4 = 3         gives remainder 0 and so are divisible by 4
12/6 = 2         gives remainder 0 and so are divisible by 6
12/12 = 1         gives remainder 0 and so are divisible by 12

Factors of 15

15/1 = 15         gives remainder 0 and so are divisible by 1
15/3 = 5         gives remainder 0 and so are divisible by 3
15/5 = 3         gives remainder 0 and so are divisible by 5
15/15 = 1         gives remainder 0 and so are divisible by 15
