How do I find the factors or divisors of the number 637,671,340?

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 637,671,340, 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.

1 637,671,340

Next, we take the number 637,671,340 and divide it by 2.

In this case, 637,671,340 ÷ 2 = 318,835,670

If the quotient is a whole number, then 2 and 318,835,670 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 318,835,670 637,671,340

Now, we try dividing 637,671,340 by 3.

637,671,340 ÷ 3 = 212,557,113.3333

If the quotient is a whole number, then 3 and 212,557,113.3333 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 2 318,835,670 637,671,340

Let's try dividing by 4.

637,671,340 ÷ 4 = 159,417,835

If the quotient is a whole number, then 4 and 159,417,835 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 4 159,417,835 318,835,670 637,671,340

We keep dividing by the next largest number, in this case the number 5. If the quotient of 637,671,340 ÷ 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:

1245102031,883,56763,767,134127,534,268159,417,835318,835,670637,671,340

All of the numbers in the table above can be evenly divided into the number 637,671,340.
