How do I find the factors or divisors of the number 512,231,520?

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 512,231,520, 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.

1 512,231,520

Next, we take the number 512,231,520 and divide it by 2.

In this case, 512,231,520 ÷ 2 = 256,115,760

If the quotient is a whole number, then 2 and 256,115,760 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 256,115,760 512,231,520

Now, we try dividing 512,231,520 by 3.

512,231,520 ÷ 3 = 170,743,840

If the quotient is a whole number, then 3 and 170,743,840 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 3 170,743,840 256,115,760 512,231,520

Let's try dividing by 4.

512,231,520 ÷ 4 = 128,057,880

If the quotient is a whole number, then 4 and 128,057,880 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 4 128,057,880 170,743,840 256,115,760 512,231,520

We keep dividing by the next largest number, in this case the number 5. If the quotient of 512,231,520 ÷ 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:
