Is 15 a factor of 19?

Here we will show you two different methods you can use to determine if 15 is a factor of 19.

The first method entails simply listing all factors of 19 and then seeing if 15 is one of them. The factors of 19 are 1 and 19. Looking at the list, you see that 15 is not on the list, and the answer to "Is 15 a factor of 19?" is therefore no.

For the second and perhaps easier method, we divide 19 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 19. If the quotient is a fractional number, then 15 is not a factor of 19.

19 divided by 15 is 1.266666667 which is a fractional number. Thus, once again, the answer to "Is 15 a factor of 19?" is no.
