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 132,020,255, it is easier to work with a table - it's called factoring from the outside in.
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 | 132,020,255 | |
| -1 | -132,020,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,020,255.
Example:
1 x 132,020,255 = 132,020,255
and
-1 x -132,020,255 = 132,020,255
Notice both answers equal 132,020,255
With that explanation out of the way, let's continue. Next, we take the number 132,020,255 and divide it by 2:
132,020,255 ÷ 2 = 66,010,127.5
If the quotient is a whole number, then 2 and 66,010,127.5 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 | 132,020,255 | |
| -1 | -132,020,255 |
Now, we try dividing 132,020,255 by 3:
132,020,255 ÷ 3 = 44,006,751.6667
If the quotient is a whole number, then 3 and 44,006,751.6667 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 | 132,020,255 | |
| -1 | -132,020,255 |
Let's try dividing by 4:
132,020,255 ÷ 4 = 33,005,063.75
If the quotient is a whole number, then 4 and 33,005,063.75 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 | 132,020,255 | |
| -1 | 132,020,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 109 | 185 | 545 | 4,033 | 6,547 | 20,165 | 32,735 | 242,239 | 713,623 | 1,211,195 | 3,568,115 | 26,404,051 | 132,020,255 |
| -1 | -5 | -37 | -109 | -185 | -545 | -4,033 | -6,547 | -20,165 | -32,735 | -242,239 | -713,623 | -1,211,195 | -3,568,115 | -26,404,051 | -132,020,255 |
