How do I find the factor combinations of the number 857,088?

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 857,088, 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.

1 857,088
-1 -857,088

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 857,088.

Example:
1 x 857,088 = 857,088
and
-1 x -857,088 = 857,088
Notice both answers equal 857,088

With that explanation out of the way, let's continue. Next, we take the number 857,088 and divide it by 2:

857,088 ÷ 2 = 428,544

If the quotient is a whole number, then 2 and 428,544 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 2 428,544 857,088
-1 -2 -428,544 -857,088

Now, we try dividing 857,088 by 3:

857,088 ÷ 3 = 285,696

If the quotient is a whole number, then 3 and 285,696 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 3 285,696 428,544 857,088
-1 -2 -3 -285,696 -428,544 -857,088

Let's try dividing by 4:

857,088 ÷ 4 = 214,272

If the quotient is a whole number, then 4 and 214,272 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 4 214,272 285,696 428,544 857,088
-1 -2 -3 -4 -214,272 -285,696 -428,544 857,088
Keep dividing by the next highest number until you cannot divide anymore.

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