How do I find the factors or divisors of the number 138,513,248?

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 138,513,248, 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.

1 138,513,248

Next, we take the number 138,513,248 and divide it by 2.

In this case, 138,513,248 ÷ 2 = 69,256,624

If the quotient is a whole number, then 2 and 69,256,624 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 69,256,624 138,513,248

Now, we try dividing 138,513,248 by 3.

138,513,248 ÷ 3 = 46,171,082.6667

If the quotient is a whole number, then 3 and 46,171,082.6667 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 69,256,624 138,513,248

Let's try dividing by 4.

138,513,248 ÷ 4 = 34,628,312

If the quotient is a whole number, then 4 and 34,628,312 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 34,628,312 69,256,624 138,513,248

We keep dividing by the next largest number, in this case the number 5. If the quotient of 138,513,248 ÷ 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:

124816324,328,5398,657,07817,314,15634,628,31269,256,624138,513,248

All of the numbers in the table above can be evenly divided into the number 138,513,248.
