How do I find the factor combinations of the number 33,707,681?

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 33,707,681, 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 33,707,681
-1 -33,707,681

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 33,707,681.

Example:
1 x 33,707,681 = 33,707,681
and
-1 x -33,707,681 = 33,707,681
Notice both answers equal 33,707,681

With that explanation out of the way, let's continue. Next, we take the number 33,707,681 and divide it by 2:

33,707,681 ÷ 2 = 16,853,840.5

If the quotient is a whole number, then 2 and 16,853,840.5 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 33,707,681
-1 -33,707,681

Now, we try dividing 33,707,681 by 3:

33,707,681 ÷ 3 = 11,235,893.6667

If the quotient is a whole number, then 3 and 11,235,893.6667 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 33,707,681
-1 -33,707,681

Let's try dividing by 4:

33,707,681 ÷ 4 = 8,426,920.25

If the quotient is a whole number, then 4 and 8,426,920.25 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 33,707,681
-1 33,707,681
Keep dividing by the next highest number until you cannot divide anymore.

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

177435,2016,48145,3674,815,38333,707,681
-1-7-743-5,201-6,481-45,367-4,815,383-33,707,681
