Is 28 a factor of 861?

Here we will show you two different methods you can use to determine if 28 is a factor of 861.

The first method entails simply listing all factors of 861 and then seeing if 28 is one of them. The factors of 861 are 1, 3, 7, 21, 41, 123, 287, and 861. Looking at the list, you see that 28 is not on the list, and the answer to "Is 28 a factor of 861?" is therefore no.

For the second and perhaps easier method, we divide 861 by 28 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 28 is a factor of 861. If the quotient is a fractional number, then 28 is not a factor of 861.

861 divided by 28 is 30.75 which is a fractional number. Thus, once again, the answer to "Is 28 a factor of 861?" is no.
