How do I find the factors or divisors of the number 315,443,316?

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 315,443,316, 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.

1 315,443,316

Next, we take the number 315,443,316 and divide it by 2.

In this case, 315,443,316 ÷ 2 = 157,721,658

If the quotient is a whole number, then 2 and 157,721,658 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 157,721,658 315,443,316

Now, we try dividing 315,443,316 by 3.

315,443,316 ÷ 3 = 105,147,772

If the quotient is a whole number, then 3 and 105,147,772 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 3 105,147,772 157,721,658 315,443,316

Let's try dividing by 4.

315,443,316 ÷ 4 = 78,860,829

If the quotient is a whole number, then 4 and 78,860,829 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 3 4 78,860,829 105,147,772 157,721,658 315,443,316

We keep dividing by the next largest number, in this case the number 5. If the quotient of 315,443,316 ÷ 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:

12346128111,6222,4333,2444,8669,73232,41364,82697,239129,652194,478388,95626,286,94352,573,88678,860,829105,147,772157,721,658315,443,316

All of the numbers in the table above can be evenly divided into the number 315,443,316.
