How do I find the factor combinations of the number 84,240,708?

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 84,240,708, 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 84,240,708
-1 -84,240,708

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 84,240,708.

Example:
1 x 84,240,708 = 84,240,708
and
-1 x -84,240,708 = 84,240,708
Notice both answers equal 84,240,708

With that explanation out of the way, let's continue. Next, we take the number 84,240,708 and divide it by 2:

84,240,708 ÷ 2 = 42,120,354

If the quotient is a whole number, then 2 and 42,120,354 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 42,120,354 84,240,708
-1 -2 -42,120,354 -84,240,708

Now, we try dividing 84,240,708 by 3:

84,240,708 ÷ 3 = 28,080,236

If the quotient is a whole number, then 3 and 28,080,236 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 28,080,236 42,120,354 84,240,708
-1 -2 -3 -28,080,236 -42,120,354 -84,240,708

Let's try dividing by 4:

84,240,708 ÷ 4 = 21,060,177

If the quotient is a whole number, then 4 and 21,060,177 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 21,060,177 28,080,236 42,120,354 84,240,708
-1 -2 -3 -4 -21,060,177 -28,080,236 -42,120,354 84,240,708
Keep dividing by the next highest number until you cannot divide anymore.

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