How do I find the factor combinations of the number 797,031?

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 797,031, 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.

1 797,031
-1 -797,031

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 797,031.

Example:
1 x 797,031 = 797,031
and
-1 x -797,031 = 797,031
Notice both answers equal 797,031

With that explanation out of the way, let's continue. Next, we take the number 797,031 and divide it by 2:

797,031 ÷ 2 = 398,515.5

If the quotient is a whole number, then 2 and 398,515.5 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:

1 797,031
-1 -797,031

Now, we try dividing 797,031 by 3:

797,031 ÷ 3 = 265,677

If the quotient is a whole number, then 3 and 265,677 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 3 265,677 797,031
-1 -3 -265,677 -797,031

Let's try dividing by 4:

797,031 ÷ 4 = 199,257.75

If the quotient is a whole number, then 4 and 199,257.75 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 3 265,677 797,031
-1 -3 -265,677 797,031
Keep dividing by the next highest number until you cannot divide anymore.

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

139195759791711772375317111,1211,5013,3634,5034,66110,08913,50913,98341,94988,559265,677797,031
