Is 8 a factor of 399?

Here we will show you two different methods you can use to determine if 8 is a factor of 399.

The first method entails simply listing all factors of 399 and then seeing if 8 is one of them. The factors of 399 are 1, 3, 7, 19, 21, 57, 133, and 399. Looking at the list, you see that 8 is not on the list, and the answer to "Is 8 a factor of 399?" is therefore no.

For the second and perhaps easier method, we divide 399 by 8 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 8 is a factor of 399. If the quotient is a fractional number, then 8 is not a factor of 399.

399 divided by 8 is 49.875 which is a fractional number. Thus, once again, the answer to "Is 8 a factor of 399?" is no.
