How do I find the factor combinations of the number 68,672,520?

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 68,672,520, 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 68,672,520
-1 -68,672,520

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 68,672,520.

Example:
1 x 68,672,520 = 68,672,520
and
-1 x -68,672,520 = 68,672,520
Notice both answers equal 68,672,520

With that explanation out of the way, let's continue. Next, we take the number 68,672,520 and divide it by 2:

68,672,520 ÷ 2 = 34,336,260

If the quotient is a whole number, then 2 and 34,336,260 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 34,336,260 68,672,520
-1 -2 -34,336,260 -68,672,520

Now, we try dividing 68,672,520 by 3:

68,672,520 ÷ 3 = 22,890,840

If the quotient is a whole number, then 3 and 22,890,840 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 22,890,840 34,336,260 68,672,520
-1 -2 -3 -22,890,840 -34,336,260 -68,672,520

Let's try dividing by 4:

68,672,520 ÷ 4 = 17,168,130

If the quotient is a whole number, then 4 and 17,168,130 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 17,168,130 22,890,840 34,336,260 68,672,520
-1 -2 -3 -4 -17,168,130 -22,890,840 -34,336,260 68,672,520
Keep dividing by the next highest number until you cannot divide anymore.

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