Is 20 a factor of 91?

Here we will show you two different methods you can use to determine if 20 is a factor of 91.

The first method entails simply listing all factors of 91 and then seeing if 20 is one of them. The factors of 91 are 1, 7, 13, and 91. Looking at the list, you see that 20 is not on the list, and the answer to "Is 20 a factor of 91?" is therefore no.

For the second and perhaps easier method, we divide 91 by 20 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 20 is a factor of 91. If the quotient is a fractional number, then 20 is not a factor of 91.

91 divided by 20 is 4.55 which is a fractional number. Thus, once again, the answer to "Is 20 a factor of 91?" is no.
