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 132,232,121, 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 | 132,232,121 | |
| -1 | -132,232,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,232,121.
Example:
1 x 132,232,121 = 132,232,121
and
-1 x -132,232,121 = 132,232,121
Notice both answers equal 132,232,121
With that explanation out of the way, let's continue. Next, we take the number 132,232,121 and divide it by 2:
132,232,121 ÷ 2 = 66,116,060.5
If the quotient is a whole number, then 2 and 66,116,060.5 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 | 132,232,121 | |
| -1 | -132,232,121 |
Now, we try dividing 132,232,121 by 3:
132,232,121 ÷ 3 = 44,077,373.6667
If the quotient is a whole number, then 3 and 44,077,373.6667 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 | 132,232,121 | |
| -1 | -132,232,121 |
Let's try dividing by 4:
132,232,121 ÷ 4 = 33,058,030.25
If the quotient is a whole number, then 4 and 33,058,030.25 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 | 132,232,121 | |
| -1 | 132,232,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 103 | 241 | 721 | 761 | 1,687 | 5,327 | 24,823 | 78,383 | 173,761 | 183,401 | 548,681 | 1,283,807 | 18,890,303 | 132,232,121 |
| -1 | -7 | -103 | -241 | -721 | -761 | -1,687 | -5,327 | -24,823 | -78,383 | -173,761 | -183,401 | -548,681 | -1,283,807 | -18,890,303 | -132,232,121 |
