How do I find the factor combinations of the number 878,976?

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 878,976, 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.

1 878,976
-1 -878,976

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 878,976.

Example:
1 x 878,976 = 878,976
and
-1 x -878,976 = 878,976
Notice both answers equal 878,976

With that explanation out of the way, let's continue. Next, we take the number 878,976 and divide it by 2:

878,976 ÷ 2 = 439,488

If the quotient is a whole number, then 2 and 439,488 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 2 439,488 878,976
-1 -2 -439,488 -878,976

Now, we try dividing 878,976 by 3:

878,976 ÷ 3 = 292,992

If the quotient is a whole number, then 3 and 292,992 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 3 292,992 439,488 878,976
-1 -2 -3 -292,992 -439,488 -878,976

Let's try dividing by 4:

878,976 ÷ 4 = 219,744

If the quotient is a whole number, then 4 and 219,744 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 4 219,744 292,992 439,488 878,976
-1 -2 -3 -4 -219,744 -292,992 -439,488 878,976
Keep dividing by the next highest number until you cannot divide anymore.

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