How do I find the factor combinations of the number 83,678,490?

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 83,678,490, 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 83,678,490
-1 -83,678,490

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 83,678,490.

Example:
1 x 83,678,490 = 83,678,490
and
-1 x -83,678,490 = 83,678,490
Notice both answers equal 83,678,490

With that explanation out of the way, let's continue. Next, we take the number 83,678,490 and divide it by 2:

83,678,490 ÷ 2 = 41,839,245

If the quotient is a whole number, then 2 and 41,839,245 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 41,839,245 83,678,490
-1 -2 -41,839,245 -83,678,490

Now, we try dividing 83,678,490 by 3:

83,678,490 ÷ 3 = 27,892,830

If the quotient is a whole number, then 3 and 27,892,830 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 27,892,830 41,839,245 83,678,490
-1 -2 -3 -27,892,830 -41,839,245 -83,678,490

Let's try dividing by 4:

83,678,490 ÷ 4 = 20,919,622.5

If the quotient is a whole number, then 4 and 20,919,622.5 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 3 27,892,830 41,839,245 83,678,490
-1 -2 -3 -27,892,830 -41,839,245 83,678,490
Keep dividing by the next highest number until you cannot divide anymore.

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