How do I find the factors or divisors of the number 523,142,109?

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 523,142,109, 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.

1 523,142,109

Next, we take the number 523,142,109 and divide it by 2.

In this case, 523,142,109 ÷ 2 = 261,571,054.5

If the quotient is a whole number, then 2 and 261,571,054.5 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 523,142,109

Now, we try dividing 523,142,109 by 3.

523,142,109 ÷ 3 = 174,380,703

If the quotient is a whole number, then 3 and 174,380,703 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 3 174,380,703 523,142,109

Let's try dividing by 4.

523,142,109 ÷ 4 = 130,785,527.25

If the quotient is a whole number, then 4 and 130,785,527.25 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 3 174,380,703 523,142,109

We keep dividing by the next largest number, in this case the number 5. If the quotient of 523,142,109 ÷ 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:
