Is 7 a factor of 990?

Here we will show you two different methods you can use to determine if 7 is a factor of 990.

The first method entails simply listing all factors of 990 and then seeing if 7 is one of them. The factors of 990 are 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, and 990. Looking at the list, you see that 7 is not on the list, and the answer to "Is 7 a factor of 990?" is therefore no.

For the second and perhaps easier method, we divide 990 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 990. If the quotient is a fractional number, then 7 is not a factor of 990.

990 divided by 7 is 141.4285714 which is a fractional number. Thus, once again, the answer to "Is 7 a factor of 990?" is no.
