Is 21 a factor of 273?

Here we will show you two different methods you can use to determine if 21 is a factor of 273.

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

For the second and perhaps easier method, we divide 273 by 21 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 21 is a factor of 273. If the quotient is a fractional number, then 21 is not a factor of 273.

273 divided by 21 is 13 which is a whole number. Thus, once again, the answer to "Is 21 a factor of 273?" is yes.
