Is 8 a factor of 405?

Here we will show you two different methods you can use to determine if 8 is a factor of 405.

The first method entails simply listing all factors of 405 and then seeing if 8 is one of them. The factors of 405 are 1, 3, 5, 9, 15, 27, 45, 81, 135, and 405. Looking at the list, you see that 8 is not on the list, and the answer to "Is 8 a factor of 405?" is therefore no.

For the second and perhaps easier method, we divide 405 by 8 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 8 is a factor of 405. If the quotient is a fractional number, then 8 is not a factor of 405.

405 divided by 8 is 50.625 which is a fractional number. Thus, once again, the answer to "Is 8 a factor of 405?" is no.
