Is 81 a factor of 490?

Here we will show you two different methods you can use to determine if 81 is a factor of 490.

The first method entails simply listing all factors of 490 and then seeing if 81 is one of them. The factors of 490 are 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, and 490. Looking at the list, you see that 81 is not on the list, and the answer to "Is 81 a factor of 490?" is therefore no.

For the second and perhaps easier method, we divide 490 by 81 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 81 is a factor of 490. If the quotient is a fractional number, then 81 is not a factor of 490.

490 divided by 81 is 6.049382716 which is a fractional number. Thus, once again, the answer to "Is 81 a factor of 490?" is no.
