How do I find the factor combinations of the number 979,096?

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 979,096, 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.

1 979,096
-1 -979,096

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 979,096.

Example:
1 x 979,096 = 979,096
and
-1 x -979,096 = 979,096
Notice both answers equal 979,096

With that explanation out of the way, let's continue. Next, we take the number 979,096 and divide it by 2:

979,096 ÷ 2 = 489,548

If the quotient is a whole number, then 2 and 489,548 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 2 489,548 979,096
-1 -2 -489,548 -979,096

Now, we try dividing 979,096 by 3:

979,096 ÷ 3 = 326,365.3333

If the quotient is a whole number, then 3 and 326,365.3333 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 2 489,548 979,096
-1 -2 -489,548 -979,096

Let's try dividing by 4:

979,096 ÷ 4 = 244,774

If the quotient is a whole number, then 4 and 244,774 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 4 244,774 489,548 979,096
-1 -2 -4 -244,774 -489,548 979,096
Keep dividing by the next highest number until you cannot divide anymore.

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

1248122,387244,774489,548979,096
-1-2-4-8-122,387-244,774-489,548-979,096
