How do I find the factors or divisors of the number 20,502,240?

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 20,502,240, 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 20,502,240

Next, we take the number 20,502,240 and divide it by 2.

In this case, 20,502,240 ÷ 2 = 10,251,120

If the quotient is a whole number, then 2 and 10,251,120 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 10,251,120 20,502,240

Now, we try dividing 20,502,240 by 3.

20,502,240 ÷ 3 = 6,834,080

If the quotient is a whole number, then 3 and 6,834,080 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 6,834,080 10,251,120 20,502,240

Let's try dividing by 4.

20,502,240 ÷ 4 = 5,125,560

If the quotient is a whole number, then 4 and 5,125,560 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 5,125,560 6,834,080 10,251,120 20,502,240

We keep dividing by the next largest number, in this case the number 5. If the quotient of 20,502,240 ÷ 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:
