Is 99 a factor of 399?

Here we will show you two different methods you can use to determine if 99 is a factor of 399.

The first method entails simply listing all factors of 399 and then seeing if 99 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 99 is not on the list, and the answer to "Is 99 a factor of 399?" is therefore no.

For the second and perhaps easier method, we divide 399 by 99 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 99 is a factor of 399. If the quotient is a fractional number, then 99 is not a factor of 399.

399 divided by 99 is 4.03030303 which is a fractional number. Thus, once again, the answer to "Is 99 a factor of 399?" is no.
