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 132,115,427, 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 | 132,115,427 | |
| -1 | -132,115,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,115,427.
Example:
1 x 132,115,427 = 132,115,427
and
-1 x -132,115,427 = 132,115,427
Notice both answers equal 132,115,427
With that explanation out of the way, let's continue. Next, we take the number 132,115,427 and divide it by 2:
132,115,427 ÷ 2 = 66,057,713.5
If the quotient is a whole number, then 2 and 66,057,713.5 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 | 132,115,427 | |
| -1 | -132,115,427 |
Now, we try dividing 132,115,427 by 3:
132,115,427 ÷ 3 = 44,038,475.6667
If the quotient is a whole number, then 3 and 44,038,475.6667 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 | 132,115,427 | |
| -1 | -132,115,427 |
Let's try dividing by 4:
132,115,427 ÷ 4 = 33,028,856.75
If the quotient is a whole number, then 4 and 33,028,856.75 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 | 132,115,427 | |
| -1 | 132,115,427 |
If you did it right, you will end up with this table:
| 1 | 23 | 89 | 233 | 277 | 2,047 | 5,359 | 6,371 | 20,737 | 24,653 | 64,541 | 476,951 | 567,019 | 1,484,443 | 5,744,149 | 132,115,427 |
| -1 | -23 | -89 | -233 | -277 | -2,047 | -5,359 | -6,371 | -20,737 | -24,653 | -64,541 | -476,951 | -567,019 | -1,484,443 | -5,744,149 | -132,115,427 |
