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 132,144,125, 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 | 132,144,125 | |
| -1 | -132,144,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,144,125.
Example:
1 x 132,144,125 = 132,144,125
and
-1 x -132,144,125 = 132,144,125
Notice both answers equal 132,144,125
With that explanation out of the way, let's continue. Next, we take the number 132,144,125 and divide it by 2:
132,144,125 ÷ 2 = 66,072,062.5
If the quotient is a whole number, then 2 and 66,072,062.5 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 | 132,144,125 | |
| -1 | -132,144,125 |
Now, we try dividing 132,144,125 by 3:
132,144,125 ÷ 3 = 44,048,041.6667
If the quotient is a whole number, then 3 and 44,048,041.6667 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 | 132,144,125 | |
| -1 | -132,144,125 |
Let's try dividing by 4:
132,144,125 ÷ 4 = 33,036,031.25
If the quotient is a whole number, then 4 and 33,036,031.25 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 | 132,144,125 | |
| -1 | 132,144,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 479 | 2,207 | 2,395 | 11,035 | 11,975 | 55,175 | 59,875 | 275,875 | 1,057,153 | 5,285,765 | 26,428,825 | 132,144,125 |
| -1 | -5 | -25 | -125 | -479 | -2,207 | -2,395 | -11,035 | -11,975 | -55,175 | -59,875 | -275,875 | -1,057,153 | -5,285,765 | -26,428,825 | -132,144,125 |
