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 132,540,317, 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 | 132,540,317 | |
| -1 | -132,540,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,540,317.
Example:
1 x 132,540,317 = 132,540,317
and
-1 x -132,540,317 = 132,540,317
Notice both answers equal 132,540,317
With that explanation out of the way, let's continue. Next, we take the number 132,540,317 and divide it by 2:
132,540,317 ÷ 2 = 66,270,158.5
If the quotient is a whole number, then 2 and 66,270,158.5 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 | 132,540,317 | |
| -1 | -132,540,317 |
Now, we try dividing 132,540,317 by 3:
132,540,317 ÷ 3 = 44,180,105.6667
If the quotient is a whole number, then 3 and 44,180,105.6667 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 | 132,540,317 | |
| -1 | -132,540,317 |
Let's try dividing by 4:
132,540,317 ÷ 4 = 33,135,079.25
If the quotient is a whole number, then 4 and 33,135,079.25 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 | 132,540,317 | |
| -1 | 132,540,317 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 173 | 1,211 | 2,249 | 8,419 | 15,743 | 58,933 | 109,447 | 766,129 | 1,456,487 | 10,195,409 | 18,934,331 | 132,540,317 |
| -1 | -7 | -13 | -91 | -173 | -1,211 | -2,249 | -8,419 | -15,743 | -58,933 | -109,447 | -766,129 | -1,456,487 | -10,195,409 | -18,934,331 | -132,540,317 |
