Is 2 a factor of 661?

Here we will show you two different methods you can use to determine if 2 is a factor of 661.

The first method entails simply listing all factors of 661 and then seeing if 2 is one of them. The factors of 661 are 1 and 661. Looking at the list, you see that 2 is not on the list, and the answer to "Is 2 a factor of 661?" is therefore no.

For the second and perhaps easier method, we divide 661 by 2 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 2 is a factor of 661. If the quotient is a fractional number, then 2 is not a factor of 661.

661 divided by 2 is 330.5 which is a fractional number. Thus, once again, the answer to "Is 2 a factor of 661?" is no.
