How do I find the factors or divisors of the number 21,252?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 21,252, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1 21,252

Next, we take the number 21,252 and divide it by 2.

In this case, 21,252 ÷ 2 = 10,626

If the quotient is a whole number, then 2 and 10,626 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 10,626 21,252

Now, we try dividing 21,252 by 3.

21,252 ÷ 3 = 7,084

If the quotient is a whole number, then 3 and 7,084 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 7,084 10,626 21,252

Let's try dividing by 4.

21,252 ÷ 4 = 5,313

If the quotient is a whole number, then 4 and 5,313 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 4 5,313 7,084 10,626 21,252

We keep dividing by the next largest number, in this case the number 5. If the quotient of 21,252 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:

123467111214212223283342444666697784921321381541612312532763083224624835066447599249661,0121,5181,7711,9323,0363,5425,3137,08410,62621,252

All of the numbers in the table above can be evenly divided into the number 21,252.

Finally, for your reference, here are all of the divisor combinations of the number 21,252:

1 x 212522 x 106263 x 70844 x 53136 x 35427 x 303611 x 193212 x 177114 x 151821 x 101222 x 96623 x 92428 x 75933 x 64442 x 50644 x 48346 x 46266 x 32269 x 30877 x 27684 x 25392 x 231132 x 161138 x 154
