Is 80 a factor of 642?

Here we will show you two different methods you can use to determine if 80 is a factor of 642.

The first method entails simply listing all factors of 642 and then seeing if 80 is one of them. The factors of 642 are 1, 2, 3, 6, 107, 214, 321, and 642. Looking at the list, you see that 80 is not on the list, and the answer to "Is 80 a factor of 642?" is therefore no.

For the second and perhaps easier method, we divide 642 by 80 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 80 is a factor of 642. If the quotient is a fractional number, then 80 is not a factor of 642.

642 divided by 80 is 8.025 which is a fractional number. Thus, once again, the answer to "Is 80 a factor of 642?" is no.
