How do I find the factor combinations of the number 984,979?

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 984,979, 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.

1 984,979
-1 -984,979

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 984,979.

Example:
1 x 984,979 = 984,979
and
-1 x -984,979 = 984,979
Notice both answers equal 984,979

With that explanation out of the way, let's continue. Next, we take the number 984,979 and divide it by 2:

984,979 ÷ 2 = 492,489.5

If the quotient is a whole number, then 2 and 492,489.5 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:

1 984,979
-1 -984,979

Now, we try dividing 984,979 by 3:

984,979 ÷ 3 = 328,326.3333

If the quotient is a whole number, then 3 and 328,326.3333 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:

1 984,979
-1 -984,979

Let's try dividing by 4:

984,979 ÷ 4 = 246,244.75

If the quotient is a whole number, then 4 and 246,244.75 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:

1 984,979
-1 984,979
Keep dividing by the next highest number until you cannot divide anymore.

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

119478931,10320,95751,841984,979
-1-19-47-893-1,103-20,957-51,841-984,979
