How do I find the factor combinations of the number 358,187,652?

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 divisors of larger numbers. To find the factor combinations of the number 358,187,652, it is easier to work with a table - it's called factoring from the outside in.

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. Then, below that, write the numbers as a negative as well.

1 358,187,652
-1 -358,187,652

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 358,187,652.

Example:
1 x 358,187,652 = 358,187,652
and
-1 x -358,187,652 = 358,187,652
Notice both answers equal 358,187,652

With that explanation out of the way, let's continue. Next, we take the number 358,187,652 and divide it by 2:

358,187,652 ÷ 2 = 179,093,826

If the quotient is a whole number, then 2 and 179,093,826 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 179,093,826 358,187,652
-1 -2 -179,093,826 -358,187,652

Now, we try dividing 358,187,652 by 3:

358,187,652 ÷ 3 = 119,395,884

If the quotient is a whole number, then 3 and 119,395,884 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 119,395,884 179,093,826 358,187,652
-1 -2 -3 -119,395,884 -179,093,826 -358,187,652

Let's try dividing by 4:

358,187,652 ÷ 4 = 89,546,913

If the quotient is a whole number, then 4 and 89,546,913 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 89,546,913 119,395,884 179,093,826 358,187,652
-1 -2 -3 -4 -89,546,913 -119,395,884 -179,093,826 358,187,652
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:
