Is 7 a factor of 398?

Here we will show you two different methods you can use to determine if 7 is a factor of 398.

The first method entails simply listing all factors of 398 and then seeing if 7 is one of them. The factors of 398 are 1, 2, 199, and 398. Looking at the list, you see that 7 is not on the list, and the answer to "Is 7 a factor of 398?" is therefore no.

For the second and perhaps easier method, we divide 398 by 7 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 7 is a factor of 398. If the quotient is a fractional number, then 7 is not a factor of 398.

398 divided by 7 is 56.85714286 which is a fractional number. Thus, once again, the answer to "Is 7 a factor of 398?" is no.
