How do I find the factor combinations of the number 20,345,325?

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 20,345,325, 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 20,345,325
-1 -20,345,325

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 20,345,325.

Example:
1 x 20,345,325 = 20,345,325
and
-1 x -20,345,325 = 20,345,325
Notice both answers equal 20,345,325

With that explanation out of the way, let's continue. Next, we take the number 20,345,325 and divide it by 2:

20,345,325 ÷ 2 = 10,172,662.5

If the quotient is a whole number, then 2 and 10,172,662.5 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 20,345,325
-1 -20,345,325

Now, we try dividing 20,345,325 by 3:

20,345,325 ÷ 3 = 6,781,775

If the quotient is a whole number, then 3 and 6,781,775 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 3 6,781,775 20,345,325
-1 -3 -6,781,775 -20,345,325

Let's try dividing by 4:

20,345,325 ÷ 4 = 5,086,331.25

If the quotient is a whole number, then 4 and 5,086,331.25 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 3 6,781,775 20,345,325
-1 -3 -6,781,775 20,345,325
Keep dividing by the next highest number until you cannot divide anymore.

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