Is 15 a factor of 520?

Here we will show you two different methods you can use to determine if 15 is a factor of 520.

The first method entails simply listing all factors of 520 and then seeing if 15 is one of them. The factors of 520 are 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, and 520. Looking at the list, you see that 15 is not on the list, and the answer to "Is 15 a factor of 520?" is therefore no.

For the second and perhaps easier method, we divide 520 by 15 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 15 is a factor of 520. If the quotient is a fractional number, then 15 is not a factor of 520.

520 divided by 15 is 34.66666667 which is a fractional number. Thus, once again, the answer to "Is 15 a factor of 520?" is no.
