Solution

Converting factors of 15

Factors are numbers that can divide without remainder.

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


We get factors of 15 numbers by finding numbers that can divide 15 without remainder or alternatively numbers that can multiply together to equal the target number being converted.

In considering numbers than can divide 15 without remainders. So we start with 1, then check 2,3,4,5,6,7,8,9, etc and 15

Getting factors is done by dividing 15 with numbers lower to it in value to find the one that will not leave remainder. Numbers that divide without remainders are the factors.
