How do I find the factor combinations of the number 123,300?

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 123,300, 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.

1 123,300
-1 -123,300

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 123,300.

Example:
1 x 123,300 = 123,300
and
-1 x -123,300 = 123,300
Notice both answers equal 123,300

With that explanation out of the way, let's continue. Next, we take the number 123,300 and divide it by 2:

123,300 ÷ 2 = 61,650

If the quotient is a whole number, then 2 and 61,650 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 61,650 123,300
-1 -2 -61,650 -123,300

Now, we try dividing 123,300 by 3:

123,300 ÷ 3 = 41,100

If the quotient is a whole number, then 3 and 41,100 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 41,100 61,650 123,300
-1 -2 -3 -41,100 -61,650 -123,300

Let's try dividing by 4:

123,300 ÷ 4 = 30,825

If the quotient is a whole number, then 4 and 30,825 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 30,825 41,100 61,650 123,300
-1 -2 -3 -4 -30,825 -41,100 -61,650 123,300
Keep dividing by the next highest number until you cannot divide anymore.

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