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 125,114,015, 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 | 125,114,015 | |
| -1 | -125,114,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,114,015.
Example:
1 x 125,114,015 = 125,114,015
and
-1 x -125,114,015 = 125,114,015
Notice both answers equal 125,114,015
With that explanation out of the way, let's continue. Next, we take the number 125,114,015 and divide it by 2:
125,114,015 ÷ 2 = 62,557,007.5
If the quotient is a whole number, then 2 and 62,557,007.5 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 | 125,114,015 | |
| -1 | -125,114,015 |
Now, we try dividing 125,114,015 by 3:
125,114,015 ÷ 3 = 41,704,671.6667
If the quotient is a whole number, then 3 and 41,704,671.6667 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 | 125,114,015 | |
| -1 | -125,114,015 |
Let's try dividing by 4:
125,114,015 ÷ 4 = 31,278,503.75
If the quotient is a whole number, then 4 and 31,278,503.75 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 | 125,114,015 | |
| -1 | 125,114,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 109 | 545 | 1,417 | 7,085 | 17,659 | 88,295 | 229,567 | 1,147,835 | 1,924,831 | 9,624,155 | 25,022,803 | 125,114,015 |
| -1 | -5 | -13 | -65 | -109 | -545 | -1,417 | -7,085 | -17,659 | -88,295 | -229,567 | -1,147,835 | -1,924,831 | -9,624,155 | -25,022,803 | -125,114,015 |
