Is 5 a factor of 255?

Here we will show you two different methods you can use to determine if 5 is a factor of 255.

The first method entails simply listing all factors of 255 and then seeing if 5 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 5 is on the list, and the answer to "Is 5 a factor of 255?" is therefore yes.

For the second and perhaps easier method, we divide 255 by 5 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 5 is a factor of 255. If the quotient is a fractional number, then 5 is not a factor of 255.

255 divided by 5 is 51 which is a whole number. Thus, once again, the answer to "Is 5 a factor of 255?" is yes.
