How do I find the factor combinations of the number 76,340,448?

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 76,340,448, 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 76,340,448
-1 -76,340,448

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 76,340,448.

Example:
1 x 76,340,448 = 76,340,448
and
-1 x -76,340,448 = 76,340,448
Notice both answers equal 76,340,448

With that explanation out of the way, let's continue. Next, we take the number 76,340,448 and divide it by 2:

76,340,448 ÷ 2 = 38,170,224

If the quotient is a whole number, then 2 and 38,170,224 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 38,170,224 76,340,448
-1 -2 -38,170,224 -76,340,448

Now, we try dividing 76,340,448 by 3:

76,340,448 ÷ 3 = 25,446,816

If the quotient is a whole number, then 3 and 25,446,816 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 25,446,816 38,170,224 76,340,448
-1 -2 -3 -25,446,816 -38,170,224 -76,340,448

Let's try dividing by 4:

76,340,448 ÷ 4 = 19,085,112

If the quotient is a whole number, then 4 and 19,085,112 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 19,085,112 25,446,816 38,170,224 76,340,448
-1 -2 -3 -4 -19,085,112 -25,446,816 -38,170,224 76,340,448
Keep dividing by the next highest number until you cannot divide anymore.

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