Is 21 a factor of 741?

Here we will show you two different methods you can use to determine if 21 is a factor of 741.

The first method entails simply listing all factors of 741 and then seeing if 21 is one of them. The factors of 741 are 1, 3, 13, 19, 39, 57, 247, and 741. Looking at the list, you see that 21 is not on the list, and the answer to "Is 21 a factor of 741?" is therefore no.

For the second and perhaps easier method, we divide 741 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 741. If the quotient is a fractional number, then 21 is not a factor of 741.

741 divided by 21 is 35.28571429 which is a fractional number. Thus, once again, the answer to "Is 21 a factor of 741?" is no.
