How do I find the factor combinations of the number 56,405,844?

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 56,405,844, 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 56,405,844
-1 -56,405,844

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 56,405,844.

Example:
1 x 56,405,844 = 56,405,844
and
-1 x -56,405,844 = 56,405,844
Notice both answers equal 56,405,844

With that explanation out of the way, let's continue. Next, we take the number 56,405,844 and divide it by 2:

56,405,844 ÷ 2 = 28,202,922

If the quotient is a whole number, then 2 and 28,202,922 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 28,202,922 56,405,844
-1 -2 -28,202,922 -56,405,844

Now, we try dividing 56,405,844 by 3:

56,405,844 ÷ 3 = 18,801,948

If the quotient is a whole number, then 3 and 18,801,948 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 18,801,948 28,202,922 56,405,844
-1 -2 -3 -18,801,948 -28,202,922 -56,405,844

Let's try dividing by 4:

56,405,844 ÷ 4 = 14,101,461

If the quotient is a whole number, then 4 and 14,101,461 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 14,101,461 18,801,948 28,202,922 56,405,844
-1 -2 -3 -4 -14,101,461 -18,801,948 -28,202,922 56,405,844
Keep dividing by the next highest number until you cannot divide anymore.

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