How do I find the factor combinations of the number 857,783,484?

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 857,783,484, 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.

1 857,783,484
-1 -857,783,484

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 857,783,484.

Example:
1 x 857,783,484 = 857,783,484
and
-1 x -857,783,484 = 857,783,484
Notice both answers equal 857,783,484

With that explanation out of the way, let's continue. Next, we take the number 857,783,484 and divide it by 2:

857,783,484 ÷ 2 = 428,891,742

If the quotient is a whole number, then 2 and 428,891,742 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 2 428,891,742 857,783,484
-1 -2 -428,891,742 -857,783,484

Now, we try dividing 857,783,484 by 3:

857,783,484 ÷ 3 = 285,927,828

If the quotient is a whole number, then 3 and 285,927,828 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 3 285,927,828 428,891,742 857,783,484
-1 -2 -3 -285,927,828 -428,891,742 -857,783,484

Let's try dividing by 4:

857,783,484 ÷ 4 = 214,445,871

If the quotient is a whole number, then 4 and 214,445,871 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 4 214,445,871 285,927,828 428,891,742 857,783,484
-1 -2 -3 -4 -214,445,871 -285,927,828 -428,891,742 857,783,484
Keep dividing by the next highest number until you cannot divide anymore.

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