How do I find the factor combinations of the number 111,243,342?

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 111,243,342, 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.

1 111,243,342
-1 -111,243,342

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 111,243,342.

Example:
1 x 111,243,342 = 111,243,342
and
-1 x -111,243,342 = 111,243,342
Notice both answers equal 111,243,342

With that explanation out of the way, let's continue. Next, we take the number 111,243,342 and divide it by 2:

111,243,342 ÷ 2 = 55,621,671

If the quotient is a whole number, then 2 and 55,621,671 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 55,621,671 111,243,342
-1 -2 -55,621,671 -111,243,342

Now, we try dividing 111,243,342 by 3:

111,243,342 ÷ 3 = 37,081,114

If the quotient is a whole number, then 3 and 37,081,114 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 37,081,114 55,621,671 111,243,342
-1 -2 -3 -37,081,114 -55,621,671 -111,243,342

Let's try dividing by 4:

111,243,342 ÷ 4 = 27,810,835.5

If the quotient is a whole number, then 4 and 27,810,835.5 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 37,081,114 55,621,671 111,243,342
-1 -2 -3 -37,081,114 -55,621,671 111,243,342
Keep dividing by the next highest number until you cannot divide anymore.

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