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 115,394,855, 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 | 115,394,855 | |
| -1 | -115,394,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,394,855.
Example:
1 x 115,394,855 = 115,394,855
and
-1 x -115,394,855 = 115,394,855
Notice both answers equal 115,394,855
With that explanation out of the way, let's continue. Next, we take the number 115,394,855 and divide it by 2:
115,394,855 ÷ 2 = 57,697,427.5
If the quotient is a whole number, then 2 and 57,697,427.5 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 | 115,394,855 | |
| -1 | -115,394,855 |
Now, we try dividing 115,394,855 by 3:
115,394,855 ÷ 3 = 38,464,951.6667
If the quotient is a whole number, then 3 and 38,464,951.6667 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 | 115,394,855 | |
| -1 | -115,394,855 |
Let's try dividing by 4:
115,394,855 ÷ 4 = 28,848,713.75
If the quotient is a whole number, then 4 and 28,848,713.75 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 | 115,394,855 | |
| -1 | 115,394,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 295 | 443 | 883 | 2,215 | 4,415 | 26,137 | 52,097 | 130,685 | 260,485 | 391,169 | 1,955,845 | 23,078,971 | 115,394,855 |
| -1 | -5 | -59 | -295 | -443 | -883 | -2,215 | -4,415 | -26,137 | -52,097 | -130,685 | -260,485 | -391,169 | -1,955,845 | -23,078,971 | -115,394,855 |
