Is 4 a factor of 810?

Here we will show you two different methods you can use to determine if 4 is a factor of 810.

The first method entails simply listing all factors of 810 and then seeing if 4 is one of them. The factors of 810 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, and 810. Looking at the list, you see that 4 is not on the list, and the answer to "Is 4 a factor of 810?" is therefore no.

For the second and perhaps easier method, we divide 810 by 4 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 4 is a factor of 810. If the quotient is a fractional number, then 4 is not a factor of 810.

810 divided by 4 is 202.5 which is a fractional number. Thus, once again, the answer to "Is 4 a factor of 810?" is no.
