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 132,003,131, 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 | 132,003,131 | |
| -1 | -132,003,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,003,131.
Example:
1 x 132,003,131 = 132,003,131
and
-1 x -132,003,131 = 132,003,131
Notice both answers equal 132,003,131
With that explanation out of the way, let's continue. Next, we take the number 132,003,131 and divide it by 2:
132,003,131 ÷ 2 = 66,001,565.5
If the quotient is a whole number, then 2 and 66,001,565.5 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 | 132,003,131 | |
| -1 | -132,003,131 |
Now, we try dividing 132,003,131 by 3:
132,003,131 ÷ 3 = 44,001,043.6667
If the quotient is a whole number, then 3 and 44,001,043.6667 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 | 132,003,131 | |
| -1 | -132,003,131 |
Let's try dividing by 4:
132,003,131 ÷ 4 = 33,000,782.75
If the quotient is a whole number, then 4 and 33,000,782.75 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 | 132,003,131 | |
| -1 | 132,003,131 |
If you did it right, you will end up with this table:
| 1 | 13 | 331 | 4,303 | 30,677 | 398,801 | 10,154,087 | 132,003,131 |
| -1 | -13 | -331 | -4,303 | -30,677 | -398,801 | -10,154,087 | -132,003,131 |
