How do I find the factor combinations of the number 126,031,350?

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 126,031,350, 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.

1 126,031,350
-1 -126,031,350

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 126,031,350.

Example:
1 x 126,031,350 = 126,031,350
and
-1 x -126,031,350 = 126,031,350
Notice both answers equal 126,031,350

With that explanation out of the way, let's continue. Next, we take the number 126,031,350 and divide it by 2:

126,031,350 ÷ 2 = 63,015,675

If the quotient is a whole number, then 2 and 63,015,675 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 63,015,675 126,031,350
-1 -2 -63,015,675 -126,031,350

Now, we try dividing 126,031,350 by 3:

126,031,350 ÷ 3 = 42,010,450

If the quotient is a whole number, then 3 and 42,010,450 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 42,010,450 63,015,675 126,031,350
-1 -2 -3 -42,010,450 -63,015,675 -126,031,350

Let's try dividing by 4:

126,031,350 ÷ 4 = 31,507,837.5

If the quotient is a whole number, then 4 and 31,507,837.5 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 2 3 42,010,450 63,015,675 126,031,350
-1 -2 -3 -42,010,450 -63,015,675 126,031,350
Keep dividing by the next highest number until you cannot divide anymore.

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