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 125,330,117, 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 | 125,330,117 | |
| -1 | -125,330,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,330,117.
Example:
1 x 125,330,117 = 125,330,117
and
-1 x -125,330,117 = 125,330,117
Notice both answers equal 125,330,117
With that explanation out of the way, let's continue. Next, we take the number 125,330,117 and divide it by 2:
125,330,117 ÷ 2 = 62,665,058.5
If the quotient is a whole number, then 2 and 62,665,058.5 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 | 125,330,117 | |
| -1 | -125,330,117 |
Now, we try dividing 125,330,117 by 3:
125,330,117 ÷ 3 = 41,776,705.6667
If the quotient is a whole number, then 3 and 41,776,705.6667 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 | 125,330,117 | |
| -1 | -125,330,117 |
Let's try dividing by 4:
125,330,117 ÷ 4 = 31,332,529.25
If the quotient is a whole number, then 4 and 31,332,529.25 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 | 125,330,117 | |
| -1 | 125,330,117 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 157 | 341 | 1,727 | 2,341 | 4,867 | 25,751 | 53,537 | 72,571 | 367,537 | 798,281 | 4,042,907 | 11,393,647 | 125,330,117 |
| -1 | -11 | -31 | -157 | -341 | -1,727 | -2,341 | -4,867 | -25,751 | -53,537 | -72,571 | -367,537 | -798,281 | -4,042,907 | -11,393,647 | -125,330,117 |
