How do I find the factor combinations of the number 51,115,752?

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 51,115,752, 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 51,115,752
-1 -51,115,752

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 51,115,752.

Example:
1 x 51,115,752 = 51,115,752
and
-1 x -51,115,752 = 51,115,752
Notice both answers equal 51,115,752

With that explanation out of the way, let's continue. Next, we take the number 51,115,752 and divide it by 2:

51,115,752 ÷ 2 = 25,557,876

If the quotient is a whole number, then 2 and 25,557,876 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 25,557,876 51,115,752
-1 -2 -25,557,876 -51,115,752

Now, we try dividing 51,115,752 by 3:

51,115,752 ÷ 3 = 17,038,584

If the quotient is a whole number, then 3 and 17,038,584 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 17,038,584 25,557,876 51,115,752
-1 -2 -3 -17,038,584 -25,557,876 -51,115,752

Let's try dividing by 4:

51,115,752 ÷ 4 = 12,778,938

If the quotient is a whole number, then 4 and 12,778,938 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 12,778,938 17,038,584 25,557,876 51,115,752
-1 -2 -3 -4 -12,778,938 -17,038,584 -25,557,876 51,115,752
Keep dividing by the next highest number until you cannot divide anymore.

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