How do I find the factor combinations of the number 879,901?

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 879,901, 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.

1 879,901
-1 -879,901

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 879,901.

Example:
1 x 879,901 = 879,901
and
-1 x -879,901 = 879,901
Notice both answers equal 879,901

With that explanation out of the way, let's continue. Next, we take the number 879,901 and divide it by 2:

879,901 ÷ 2 = 439,950.5

If the quotient is a whole number, then 2 and 439,950.5 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:

1 879,901
-1 -879,901

Now, we try dividing 879,901 by 3:

879,901 ÷ 3 = 293,300.3333

If the quotient is a whole number, then 3 and 293,300.3333 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:

1 879,901
-1 -879,901

Let's try dividing by 4:

879,901 ÷ 4 = 219,975.25

If the quotient is a whole number, then 4 and 219,975.25 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:

1 879,901
-1 879,901
Keep dividing by the next highest number until you cannot divide anymore.

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

111414511,95121,46179,991879,901
-1-11-41-451-1,951-21,461-79,991-879,901
