How do I find the factors or divisors of the number 311,115,748?

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 311,115,748, 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.

1 311,115,748

Next, we take the number 311,115,748 and divide it by 2.

In this case, 311,115,748 ÷ 2 = 155,557,874

If the quotient is a whole number, then 2 and 155,557,874 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 155,557,874 311,115,748

Now, we try dividing 311,115,748 by 3.

311,115,748 ÷ 3 = 103,705,249.3333

If the quotient is a whole number, then 3 and 103,705,249.3333 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 2 155,557,874 311,115,748

Let's try dividing by 4.

311,115,748 ÷ 4 = 77,778,937

If the quotient is a whole number, then 4 and 77,778,937 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 77,778,937 155,557,874 311,115,748

We keep dividing by the next largest number, in this case the number 5. If the quotient of 311,115,748 ÷ 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:

12447941881,654,8713,309,7426,619,48477,778,937155,557,874311,115,748
