Divisors of 21

Here we will define what "the divisors of 21" means and show you how to find the divisors of 21.

First, note that in a division problem like x divided by y equals z, x is the dividend, y is the divisor, and z is the quotient as illustrated here:

Dividend / Divisor = Quotient

Divisors of 21 are all the unique whole number divisors that make the quotient a whole number if you make the dividend 21:

21 / Divisor = Quotient

To find all the divisors of 21, we first divide 21 by every whole number up to 21 like so:

21 / 1 = 21
21 / 2 = 10.5
21 / 3 = 7
21 / 4 = 5.25
etc...

Then, we take the divisors from the list above if the quotient was a whole number. This new list is the Divisors of 21.

The Divisors of 21 are as follows:

1, 3, 7, and 21.
