Is 15 a factor of 523?

Here we will show you two different methods you can use to determine if 15 is a factor of 523.

The first method entails simply listing all factors of 523 and then seeing if 15 is one of them. The factors of 523 are 1 and 523. Looking at the list, you see that 15 is not on the list, and the answer to "Is 15 a factor of 523?" is therefore no.

For the second and perhaps easier method, we divide 523 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 523. If the quotient is a fractional number, then 15 is not a factor of 523.

523 divided by 15 is 34.86666667 which is a fractional number. Thus, once again, the answer to "Is 15 a factor of 523?" is no.
