Is 31 a factor of 765?

Here we will show you two different methods you can use to determine if 31 is a factor of 765.

The first method entails simply listing all factors of 765 and then seeing if 31 is one of them. The factors of 765 are 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, and 765. Looking at the list, you see that 31 is not on the list, and the answer to "Is 31 a factor of 765?" is therefore no.

For the second and perhaps easier method, we divide 765 by 31 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 31 is a factor of 765. If the quotient is a fractional number, then 31 is not a factor of 765.

765 divided by 31 is 24.67741935 which is a fractional number. Thus, once again, the answer to "Is 31 a factor of 765?" is no.
