How do I find the factor combinations of the number 686,684,376?

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 686,684,376, 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.

1 686,684,376
-1 -686,684,376

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 686,684,376.

Example:
1 x 686,684,376 = 686,684,376
and
-1 x -686,684,376 = 686,684,376
Notice both answers equal 686,684,376

With that explanation out of the way, let's continue. Next, we take the number 686,684,376 and divide it by 2:

686,684,376 ÷ 2 = 343,342,188

If the quotient is a whole number, then 2 and 343,342,188 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 2 343,342,188 686,684,376
-1 -2 -343,342,188 -686,684,376

Now, we try dividing 686,684,376 by 3:

686,684,376 ÷ 3 = 228,894,792

If the quotient is a whole number, then 3 and 228,894,792 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 3 228,894,792 343,342,188 686,684,376
-1 -2 -3 -228,894,792 -343,342,188 -686,684,376

Let's try dividing by 4:

686,684,376 ÷ 4 = 171,671,094

If the quotient is a whole number, then 4 and 171,671,094 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 3 4 171,671,094 228,894,792 343,342,188 686,684,376
-1 -2 -3 -4 -171,671,094 -228,894,792 -343,342,188 686,684,376
Keep dividing by the next highest number until you cannot divide anymore.

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