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 125,662,255, 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 | 125,662,255 | |
| -1 | -125,662,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,662,255.
Example:
1 x 125,662,255 = 125,662,255
and
-1 x -125,662,255 = 125,662,255
Notice both answers equal 125,662,255
With that explanation out of the way, let's continue. Next, we take the number 125,662,255 and divide it by 2:
125,662,255 ÷ 2 = 62,831,127.5
If the quotient is a whole number, then 2 and 62,831,127.5 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 | 125,662,255 | |
| -1 | -125,662,255 |
Now, we try dividing 125,662,255 by 3:
125,662,255 ÷ 3 = 41,887,418.3333
If the quotient is a whole number, then 3 and 41,887,418.3333 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 | 125,662,255 | |
| -1 | -125,662,255 |
Let's try dividing by 4:
125,662,255 ÷ 4 = 31,415,563.75
If the quotient is a whole number, then 4 and 31,415,563.75 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 | 125,662,255 | |
| -1 | 125,662,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 139 | 235 | 695 | 3,847 | 6,533 | 19,235 | 32,665 | 180,809 | 534,733 | 904,045 | 2,673,665 | 25,132,451 | 125,662,255 |
| -1 | -5 | -47 | -139 | -235 | -695 | -3,847 | -6,533 | -19,235 | -32,665 | -180,809 | -534,733 | -904,045 | -2,673,665 | -25,132,451 | -125,662,255 |
