How do I find the factors or divisors of the number 631,423,172?

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 631,423,172, 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.

1 631,423,172

Next, we take the number 631,423,172 and divide it by 2.

In this case, 631,423,172 ÷ 2 = 315,711,586

If the quotient is a whole number, then 2 and 315,711,586 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 315,711,586 631,423,172

Now, we try dividing 631,423,172 by 3.

631,423,172 ÷ 3 = 210,474,390.6667

If the quotient is a whole number, then 3 and 210,474,390.6667 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 2 315,711,586 631,423,172

Let's try dividing by 4.

631,423,172 ÷ 4 = 157,855,793

If the quotient is a whole number, then 4 and 157,855,793 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 4 157,855,793 315,711,586 631,423,172

We keep dividing by the next largest number, in this case the number 5. If the quotient of 631,423,172 ÷ 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:

1241272545081,242,9592,485,9184,971,836157,855,793315,711,586631,423,172

All of the numbers in the table above can be evenly divided into the number 631,423,172.
