Is 21 a factor of 693?

Here we will show you two different methods you can use to determine if 21 is a factor of 693.

The first method entails simply listing all factors of 693 and then seeing if 21 is one of them. The factors of 693 are 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, and 693. Looking at the list, you see that 21 is on the list, and the answer to "Is 21 a factor of 693?" is therefore yes.

For the second and perhaps easier method, we divide 693 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 693. If the quotient is a fractional number, then 21 is not a factor of 693.

693 divided by 21 is 33 which is a whole number. Thus, once again, the answer to "Is 21 a factor of 693?" is yes.
