Question

List all the factors of 45

Answer 1

Well let's see
I can divide it by 5
45 = 5 * 9
but I can divide 9 by 3
45 = 5 * 3 *3

There is not much more I can do. Those must be the "prime" factors.

Answer 2

Answer 3

Of course you better make sure that 3 times 3 times 5 is what we hope it is!!
