How do I find the factor combinations of the number 133,756?

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 133,756, 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.

1 133,756
-1 -133,756

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 133,756.

Example:
1 x 133,756 = 133,756
and
-1 x -133,756 = 133,756
Notice both answers equal 133,756

With that explanation out of the way, let's continue. Next, we take the number 133,756 and divide it by 2:

133,756 ÷ 2 = 66,878

If the quotient is a whole number, then 2 and 66,878 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 66,878 133,756
-1 -2 -66,878 -133,756

Now, we try dividing 133,756 by 3:

133,756 ÷ 3 = 44,585.3333

If the quotient is a whole number, then 3 and 44,585.3333 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 66,878 133,756
-1 -2 -66,878 -133,756

Let's try dividing by 4:

133,756 ÷ 4 = 33,439

If the quotient is a whole number, then 4 and 33,439 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 33,439 66,878 133,756
-1 -2 -4 -33,439 -66,878 133,756
Keep dividing by the next highest number until you cannot divide anymore.

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