How do I find the factors or divisors of the number 331,133,428?

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 331,133,428, 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.

1 331,133,428

Next, we take the number 331,133,428 and divide it by 2.

In this case, 331,133,428 ÷ 2 = 165,566,714

If the quotient is a whole number, then 2 and 165,566,714 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 165,566,714 331,133,428

Now, we try dividing 331,133,428 by 3.

331,133,428 ÷ 3 = 110,377,809.3333

If the quotient is a whole number, then 3 and 110,377,809.3333 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 2 165,566,714 331,133,428

Let's try dividing by 4.

331,133,428 ÷ 4 = 82,783,357

If the quotient is a whole number, then 4 and 82,783,357 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 82,783,357 165,566,714 331,133,428

We keep dividing by the next largest number, in this case the number 5. If the quotient of 331,133,428 ÷ 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:

124149298596555,5931,111,1862,222,37282,783,357165,566,714331,133,428

All of the numbers in the table above can be evenly divided into the number 331,133,428.
