How do I find the factor combinations of the number 68,588,435?

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 68,588,435, 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 68,588,435
-1 -68,588,435

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 68,588,435.

Example:
1 x 68,588,435 = 68,588,435
and
-1 x -68,588,435 = 68,588,435
Notice both answers equal 68,588,435

With that explanation out of the way, let's continue. Next, we take the number 68,588,435 and divide it by 2:

68,588,435 ÷ 2 = 34,294,217.5

If the quotient is a whole number, then 2 and 34,294,217.5 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 68,588,435
-1 -68,588,435

Now, we try dividing 68,588,435 by 3:

68,588,435 ÷ 3 = 22,862,811.6667

If the quotient is a whole number, then 3 and 22,862,811.6667 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 68,588,435
-1 -68,588,435

Let's try dividing by 4:

68,588,435 ÷ 4 = 17,147,108.75

If the quotient is a whole number, then 4 and 17,147,108.75 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 68,588,435
-1 68,588,435
Keep dividing by the next highest number until you cannot divide anymore.

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

1513,717,68768,588,435
-1-5-13,717,687-68,588,435
