How do I find the factors or divisors of the number 168,637,356?

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 168,637,356, 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.

1 168,637,356

Next, we take the number 168,637,356 and divide it by 2.

In this case, 168,637,356 ÷ 2 = 84,318,678

If the quotient is a whole number, then 2 and 84,318,678 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 84,318,678 168,637,356

Now, we try dividing 168,637,356 by 3.

168,637,356 ÷ 3 = 56,212,452

If the quotient is a whole number, then 3 and 56,212,452 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 56,212,452 84,318,678 168,637,356

Let's try dividing by 4.

168,637,356 ÷ 4 = 42,159,339

If the quotient is a whole number, then 4 and 42,159,339 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 42,159,339 56,212,452 84,318,678 168,637,356

We keep dividing by the next largest number, in this case the number 5. If the quotient of 168,637,356 ÷ 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:

12346912182736541081,561,4573,122,9144,684,3716,245,8289,368,74214,053,11318,737,48428,106,22642,159,33956,212,45284,318,678168,637,356

All of the numbers in the table above can be evenly divided into the number 168,637,356.
