How do I find the factor combinations of the number 8,424,384?

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 8,424,384, 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 8,424,384
-1 -8,424,384

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 8,424,384.

Example:
1 x 8,424,384 = 8,424,384
and
-1 x -8,424,384 = 8,424,384
Notice both answers equal 8,424,384

With that explanation out of the way, let's continue. Next, we take the number 8,424,384 and divide it by 2:

8,424,384 ÷ 2 = 4,212,192

If the quotient is a whole number, then 2 and 4,212,192 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 4,212,192 8,424,384
-1 -2 -4,212,192 -8,424,384

Now, we try dividing 8,424,384 by 3:

8,424,384 ÷ 3 = 2,808,128

If the quotient is a whole number, then 3 and 2,808,128 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 2,808,128 4,212,192 8,424,384
-1 -2 -3 -2,808,128 -4,212,192 -8,424,384

Let's try dividing by 4:

8,424,384 ÷ 4 = 2,106,096

If the quotient is a whole number, then 4 and 2,106,096 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 2,106,096 2,808,128 4,212,192 8,424,384
-1 -2 -3 -4 -2,106,096 -2,808,128 -4,212,192 8,424,384
Keep dividing by the next highest number until you cannot divide anymore.

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