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 115,884,755, 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 | 115,884,755 | |
| -1 | -115,884,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,884,755.
Example:
1 x 115,884,755 = 115,884,755
and
-1 x -115,884,755 = 115,884,755
Notice both answers equal 115,884,755
With that explanation out of the way, let's continue. Next, we take the number 115,884,755 and divide it by 2:
115,884,755 ÷ 2 = 57,942,377.5
If the quotient is a whole number, then 2 and 57,942,377.5 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 | 115,884,755 | |
| -1 | -115,884,755 |
Now, we try dividing 115,884,755 by 3:
115,884,755 ÷ 3 = 38,628,251.6667
If the quotient is a whole number, then 3 and 38,628,251.6667 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 | 115,884,755 | |
| -1 | -115,884,755 |
Let's try dividing by 4:
115,884,755 ÷ 4 = 28,971,188.75
If the quotient is a whole number, then 4 and 28,971,188.75 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 | 115,884,755 | |
| -1 | 115,884,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 331 | 1,429 | 1,655 | 2,317 | 7,145 | 10,003 | 11,585 | 16,219 | 50,015 | 70,021 | 81,095 | 350,105 | 472,999 | 2,364,995 | 3,310,993 | 16,554,965 | 23,176,951 | 115,884,755 |
| -1 | -5 | -7 | -35 | -49 | -245 | -331 | -1,429 | -1,655 | -2,317 | -7,145 | -10,003 | -11,585 | -16,219 | -50,015 | -70,021 | -81,095 | -350,105 | -472,999 | -2,364,995 | -3,310,993 | -16,554,965 | -23,176,951 | -115,884,755 |
