How do I find the factor combinations of the number 622,705,523?

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 622,705,523, 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.

1 622,705,523
-1 -622,705,523

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 622,705,523.

Example:
1 x 622,705,523 = 622,705,523
and
-1 x -622,705,523 = 622,705,523
Notice both answers equal 622,705,523

With that explanation out of the way, let's continue. Next, we take the number 622,705,523 and divide it by 2:

622,705,523 ÷ 2 = 311,352,761.5

If the quotient is a whole number, then 2 and 311,352,761.5 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:

1 622,705,523
-1 -622,705,523

Now, we try dividing 622,705,523 by 3:

622,705,523 ÷ 3 = 207,568,507.6667

If the quotient is a whole number, then 3 and 207,568,507.6667 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:

1 622,705,523
-1 -622,705,523

Let's try dividing by 4:

622,705,523 ÷ 4 = 155,676,380.75

If the quotient is a whole number, then 4 and 155,676,380.75 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:

1 622,705,523
-1 622,705,523
Keep dividing by the next highest number until you cannot divide anymore.

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

111374071,529,98916,829,87956,609,593622,705,523
-1-11-37-407-1,529,989-16,829,879-56,609,593-622,705,523
