Is 20 a factor of 421?

Here we will show you two different methods you can use to determine if 20 is a factor of 421.

The first method entails simply listing all factors of 421 and then seeing if 20 is one of them. The factors of 421 are 1 and 421. Looking at the list, you see that 20 is not on the list, and the answer to "Is 20 a factor of 421?" is therefore no.

For the second and perhaps easier method, we divide 421 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 421. If the quotient is a fractional number, then 20 is not a factor of 421.

421 divided by 20 is 21.05 which is a fractional number. Thus, once again, the answer to "Is 20 a factor of 421?" is no.
