Is 21 a factor of 735?

Here we will show you two different methods you can use to determine if 21 is a factor of 735.

The first method entails simply listing all factors of 735 and then seeing if 21 is one of them. The factors of 735 are 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, and 735. Looking at the list, you see that 21 is on the list, and the answer to "Is 21 a factor of 735?" is therefore yes.

For the second and perhaps easier method, we divide 735 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 735. If the quotient is a fractional number, then 21 is not a factor of 735.

735 divided by 21 is 35 which is a whole number. Thus, once again, the answer to "Is 21 a factor of 735?" is yes.
