How do I find the factor combinations of the number 181,055?

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 181,055, 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.

1 181,055
-1 -181,055

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 181,055.

Example:
1 x 181,055 = 181,055
and
-1 x -181,055 = 181,055
Notice both answers equal 181,055

With that explanation out of the way, let's continue. Next, we take the number 181,055 and divide it by 2:

181,055 ÷ 2 = 90,527.5

If the quotient is a whole number, then 2 and 90,527.5 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:

1 181,055
-1 -181,055

Now, we try dividing 181,055 by 3:

181,055 ÷ 3 = 60,351.6667

If the quotient is a whole number, then 3 and 60,351.6667 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:

1 181,055
-1 -181,055

Let's try dividing by 4:

181,055 ÷ 4 = 45,263.75

If the quotient is a whole number, then 4 and 45,263.75 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:

1 181,055
-1 181,055
Keep dividing by the next highest number until you cannot divide anymore.

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

15735492457393,6955,17325,86536,211181,055
-1-5-7-35-49-245-739-3,695-5,173-25,865-36,211-181,055
