How do I find the factors or divisors of the number 20,531,320?

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 20,531,320, 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 20,531,320

Next, we take the number 20,531,320 and divide it by 2.

In this case, 20,531,320 ÷ 2 = 10,265,660

If the quotient is a whole number, then 2 and 10,265,660 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 10,265,660 20,531,320

Now, we try dividing 20,531,320 by 3.

20,531,320 ÷ 3 = 6,843,773.3333

If the quotient is a whole number, then 3 and 6,843,773.3333 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 10,265,660 20,531,320

Let's try dividing by 4.

20,531,320 ÷ 4 = 5,132,830

If the quotient is a whole number, then 4 and 5,132,830 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 4 5,132,830 10,265,660 20,531,320

We keep dividing by the next largest number, in this case the number 5. If the quotient of 20,531,320 ÷ 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:

12458102040513,2831,026,5662,053,1322,566,4154,106,2645,132,83010,265,66020,531,320

All of the numbers in the table above can be evenly divided into the number 20,531,320.

Finally, for your reference, here are all of the divisor combinations of the number 20,531,320:
