What Are the Factors of 15?

The factors of 15 are 1, 3, 5, 15.

Calcating the factors of 15 is straightforward. 1 and 15 are the first two factors.


  1. Try 1. 1 x 15 = 15, so put these into our factor list.
    1...15

  2. Take 2... no good. 15/2 isn't a whole number. So we skip 2.

  3. Now take 3. 3 x 5 = 15, so now we put these in our list of factors.
    13...515

  4. Next try 4... no luck. 15/4 isn't a whole number. So we skip 4.

  5. Now, since we don't have any more numbers to try, we're done!
