To find the factors of a number, you first need to split that number into its prime factors. In the case of 15, this produces:

15 = 3x5

The next step is to note that every factor of the number (apart from 1) is the product of any combination of its prime factors. Thus, the factors of 15 are:

1, 3, 5 and 15.
