How do I find the factor combinations of the number 868,924?

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 868,924, 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.

1 868,924
-1 -868,924

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 868,924.

Example:
1 x 868,924 = 868,924
and
-1 x -868,924 = 868,924
Notice both answers equal 868,924

With that explanation out of the way, let's continue. Next, we take the number 868,924 and divide it by 2:

868,924 ÷ 2 = 434,462

If the quotient is a whole number, then 2 and 434,462 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 2 434,462 868,924
-1 -2 -434,462 -868,924

Now, we try dividing 868,924 by 3:

868,924 ÷ 3 = 289,641.3333

If the quotient is a whole number, then 3 and 289,641.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 2 434,462 868,924
-1 -2 -434,462 -868,924

Let's try dividing by 4:

868,924 ÷ 4 = 217,231

If the quotient is a whole number, then 4 and 217,231 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 4 217,231 434,462 868,924
-1 -2 -4 -217,231 -434,462 868,924
Keep dividing by the next highest number until you cannot divide anymore.

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

1247142831,03362,066124,132217,231434,462868,924
-1-2-4-7-14-28-31,033-62,066-124,132-217,231-434,462-868,924
