How do I find the factor combinations of the number 120,650,436?

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 120,650,436, 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.

1 120,650,436
-1 -120,650,436

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 120,650,436.

Example:
1 x 120,650,436 = 120,650,436
and
-1 x -120,650,436 = 120,650,436
Notice both answers equal 120,650,436

With that explanation out of the way, let's continue. Next, we take the number 120,650,436 and divide it by 2:

120,650,436 ÷ 2 = 60,325,218

If the quotient is a whole number, then 2 and 60,325,218 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 60,325,218 120,650,436
-1 -2 -60,325,218 -120,650,436

Now, we try dividing 120,650,436 by 3:

120,650,436 ÷ 3 = 40,216,812

If the quotient is a whole number, then 3 and 40,216,812 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 40,216,812 60,325,218 120,650,436
-1 -2 -3 -40,216,812 -60,325,218 -120,650,436

Let's try dividing by 4:

120,650,436 ÷ 4 = 30,162,609

If the quotient is a whole number, then 4 and 30,162,609 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 30,162,609 40,216,812 60,325,218 120,650,436
-1 -2 -3 -4 -30,162,609 -40,216,812 -60,325,218 120,650,436
Keep dividing by the next highest number until you cannot divide anymore.

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