How do I find the factor combinations of the number 41,680,920?

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 41,680,920, 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 41,680,920
-1 -41,680,920

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 41,680,920.

Example:
1 x 41,680,920 = 41,680,920
and
-1 x -41,680,920 = 41,680,920
Notice both answers equal 41,680,920

With that explanation out of the way, let's continue. Next, we take the number 41,680,920 and divide it by 2:

41,680,920 ÷ 2 = 20,840,460

If the quotient is a whole number, then 2 and 20,840,460 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 20,840,460 41,680,920
-1 -2 -20,840,460 -41,680,920

Now, we try dividing 41,680,920 by 3:

41,680,920 ÷ 3 = 13,893,640

If the quotient is a whole number, then 3 and 13,893,640 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 13,893,640 20,840,460 41,680,920
-1 -2 -3 -13,893,640 -20,840,460 -41,680,920

Let's try dividing by 4:

41,680,920 ÷ 4 = 10,420,230

If the quotient is a whole number, then 4 and 10,420,230 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 10,420,230 13,893,640 20,840,460 41,680,920
-1 -2 -3 -4 -10,420,230 -13,893,640 -20,840,460 41,680,920
Keep dividing by the next highest number until you cannot divide anymore.

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