How do I find the factor combinations of the number 36,231,881?

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 36,231,881, 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 36,231,881
-1 -36,231,881

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 36,231,881.

Example:
1 x 36,231,881 = 36,231,881
and
-1 x -36,231,881 = 36,231,881
Notice both answers equal 36,231,881

With that explanation out of the way, let's continue. Next, we take the number 36,231,881 and divide it by 2:

36,231,881 ÷ 2 = 18,115,940.5

If the quotient is a whole number, then 2 and 18,115,940.5 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 36,231,881
-1 -36,231,881

Now, we try dividing 36,231,881 by 3:

36,231,881 ÷ 3 = 12,077,293.6667

If the quotient is a whole number, then 3 and 12,077,293.6667 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 36,231,881
-1 -36,231,881

Let's try dividing by 4:

36,231,881 ÷ 4 = 9,057,970.25

If the quotient is a whole number, then 4 and 9,057,970.25 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 36,231,881
-1 36,231,881
Keep dividing by the next highest number until you cannot divide anymore.

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

173372,35915,359107,5135,175,98336,231,881
