How do I find the factor combinations of the number 68,068,850?

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 68,068,850, 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 68,068,850
-1 -68,068,850

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 68,068,850.

Example:
1 x 68,068,850 = 68,068,850
and
-1 x -68,068,850 = 68,068,850
Notice both answers equal 68,068,850

With that explanation out of the way, let's continue. Next, we take the number 68,068,850 and divide it by 2:

68,068,850 ÷ 2 = 34,034,425

If the quotient is a whole number, then 2 and 34,034,425 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 2 34,034,425 68,068,850
-1 -2 -34,034,425 -68,068,850

Now, we try dividing 68,068,850 by 3:

68,068,850 ÷ 3 = 22,689,616.6667

If the quotient is a whole number, then 3 and 22,689,616.6667 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 2 34,034,425 68,068,850
-1 -2 -34,034,425 -68,068,850

Let's try dividing by 4:

68,068,850 ÷ 4 = 17,017,212.5

If the quotient is a whole number, then 4 and 17,017,212.5 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 2 34,034,425 68,068,850
-1 -2 -34,034,425 68,068,850
Keep dividing by the next highest number until you cannot divide anymore.

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