Is 20 a factor of 255?

Here we will show you two different methods you can use to determine if 20 is a factor of 255.

The first method entails simply listing all factors of 255 and then seeing if 20 is one of them. The factors of 255 are 1, 3, 5, 15, 17, 51, 85, and 255. Looking at the list, you see that 20 is not on the list, and the answer to "Is 20 a factor of 255?" is therefore no.

For the second and perhaps easier method, we divide 255 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 255. If the quotient is a fractional number, then 20 is not a factor of 255.

255 divided by 20 is 12.75 which is a fractional number. Thus, once again, the answer to "Is 20 a factor of 255?" is no.
