How do I find the factors or divisors of the number 21,459,684?

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 21,459,684, 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 21,459,684

Next, we take the number 21,459,684 and divide it by 2.

In this case, 21,459,684 ÷ 2 = 10,729,842

If the quotient is a whole number, then 2 and 10,729,842 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 10,729,842 21,459,684

Now, we try dividing 21,459,684 by 3.

21,459,684 ÷ 3 = 7,153,228

If the quotient is a whole number, then 3 and 7,153,228 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 7,153,228 10,729,842 21,459,684

Let's try dividing by 4.

21,459,684 ÷ 4 = 5,364,921

If the quotient is a whole number, then 4 and 5,364,921 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 5,364,921 7,153,228 10,729,842 21,459,684

We keep dividing by the next largest number, in this case the number 5. If the quotient of 21,459,684 ÷ 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:

12346121,1931,4992,3862,9983,5794,4974,7725,9967,1588,99414,31617,9881,788,3073,576,6145,364,9217,153,22810,729,84221,459,684

All of the numbers in the table above can be evenly divided into the number 21,459,684.
