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 125,115,055, 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 | 125,115,055 | |
| -1 | -125,115,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,115,055.
Example:
1 x 125,115,055 = 125,115,055
and
-1 x -125,115,055 = 125,115,055
Notice both answers equal 125,115,055
With that explanation out of the way, let's continue. Next, we take the number 125,115,055 and divide it by 2:
125,115,055 ÷ 2 = 62,557,527.5
If the quotient is a whole number, then 2 and 62,557,527.5 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 | 125,115,055 | |
| -1 | -125,115,055 |
Now, we try dividing 125,115,055 by 3:
125,115,055 ÷ 3 = 41,705,018.3333
If the quotient is a whole number, then 3 and 41,705,018.3333 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 | 125,115,055 | |
| -1 | -125,115,055 |
Let's try dividing by 4:
125,115,055 ÷ 4 = 31,278,763.75
If the quotient is a whole number, then 4 and 31,278,763.75 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 | 125,115,055 | |
| -1 | 125,115,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 1,495 | 83,689 | 418,445 | 1,087,957 | 1,924,847 | 5,439,785 | 9,624,235 | 25,023,011 | 125,115,055 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -1,495 | -83,689 | -418,445 | -1,087,957 | -1,924,847 | -5,439,785 | -9,624,235 | -25,023,011 | -125,115,055 |
