Is 3 a factor of 819?

Here we will show you two different methods you can use to determine if 3 is a factor of 819.

The first method entails simply listing all factors of 819 and then seeing if 3 is one of them. The factors of 819 are 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, and 819. Looking at the list, you see that 3 is on the list, and the answer to "Is 3 a factor of 819?" is therefore yes.

For the second and perhaps easier method, we divide 819 by 3 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 3 is a factor of 819. If the quotient is a fractional number, then 3 is not a factor of 819.

819 divided by 3 is 273 which is a whole number. Thus, once again, the answer to "Is 3 a factor of 819?" is yes.
