How do I find the factor combinations of the number 115,376?

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 115,376, 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.

1 115,376
-1 -115,376

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 115,376.

Example:
1 x 115,376 = 115,376
and
-1 x -115,376 = 115,376
Notice both answers equal 115,376

With that explanation out of the way, let's continue. Next, we take the number 115,376 and divide it by 2:

115,376 ÷ 2 = 57,688

If the quotient is a whole number, then 2 and 57,688 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 57,688 115,376
-1 -2 -57,688 -115,376

Now, we try dividing 115,376 by 3:

115,376 ÷ 3 = 38,458.6667

If the quotient is a whole number, then 3 and 38,458.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 2 57,688 115,376
-1 -2 -57,688 -115,376

Let's try dividing by 4:

115,376 ÷ 4 = 28,844

If the quotient is a whole number, then 4 and 28,844 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 4 28,844 57,688 115,376
-1 -2 -4 -28,844 -57,688 115,376
Keep dividing by the next highest number until you cannot divide anymore.

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

1248167,21114,42228,84457,688115,376
