How do I find the factor combinations of the number 132,065,605?

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 132,065,605, 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.

1 132,065,605
-1 -132,065,605

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 132,065,605.

Example:
1 x 132,065,605 = 132,065,605
and
-1 x -132,065,605 = 132,065,605
Notice both answers equal 132,065,605

With that explanation out of the way, let's continue. Next, we take the number 132,065,605 and divide it by 2:

132,065,605 ÷ 2 = 66,032,802.5

If the quotient is a whole number, then 2 and 66,032,802.5 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:

1 132,065,605
-1 -132,065,605

Now, we try dividing 132,065,605 by 3:

132,065,605 ÷ 3 = 44,021,868.3333

If the quotient is a whole number, then 3 and 44,021,868.3333 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:

1 132,065,605
-1 -132,065,605

Let's try dividing by 4:

132,065,605 ÷ 4 = 33,016,401.25

If the quotient is a whole number, then 4 and 33,016,401.25 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:

1 132,065,605
-1 132,065,605
Keep dividing by the next highest number until you cannot divide anymore.

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