How do I find the factor combinations of the number 111,976?

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 111,976, 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.

1 111,976
-1 -111,976

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 111,976.

Example:
1 x 111,976 = 111,976
and
-1 x -111,976 = 111,976
Notice both answers equal 111,976

With that explanation out of the way, let's continue. Next, we take the number 111,976 and divide it by 2:

111,976 ÷ 2 = 55,988

If the quotient is a whole number, then 2 and 55,988 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 55,988 111,976
-1 -2 -55,988 -111,976

Now, we try dividing 111,976 by 3:

111,976 ÷ 3 = 37,325.3333

If the quotient is a whole number, then 3 and 37,325.3333 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 55,988 111,976
-1 -2 -55,988 -111,976

Let's try dividing by 4:

111,976 ÷ 4 = 27,994

If the quotient is a whole number, then 4 and 27,994 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 27,994 55,988 111,976
-1 -2 -4 -27,994 -55,988 111,976
Keep dividing by the next highest number until you cannot divide anymore.

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

124813,99727,99455,988111,976
-1-2-4-8-13,997-27,994-55,988-111,976
