How do I find the factor combinations of the number 82,022,681?

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 82,022,681, 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 82,022,681
-1 -82,022,681

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 82,022,681.

Example:
1 x 82,022,681 = 82,022,681
and
-1 x -82,022,681 = 82,022,681
Notice both answers equal 82,022,681

With that explanation out of the way, let's continue. Next, we take the number 82,022,681 and divide it by 2:

82,022,681 ÷ 2 = 41,011,340.5

If the quotient is a whole number, then 2 and 41,011,340.5 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 82,022,681
-1 -82,022,681

Now, we try dividing 82,022,681 by 3:

82,022,681 ÷ 3 = 27,340,893.6667

If the quotient is a whole number, then 3 and 27,340,893.6667 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 82,022,681
-1 -82,022,681

Let's try dividing by 4:

82,022,681 ÷ 4 = 20,505,670.25

If the quotient is a whole number, then 4 and 20,505,670.25 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 82,022,681
-1 82,022,681
Keep dividing by the next highest number until you cannot divide anymore.

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

1136,309,43782,022,681
-1-13-6,309,437-82,022,681
