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 115,816,883, 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 | 115,816,883 | |
| -1 | -115,816,883 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,816,883.
Example:
1 x 115,816,883 = 115,816,883
and
-1 x -115,816,883 = 115,816,883
Notice both answers equal 115,816,883
With that explanation out of the way, let's continue. Next, we take the number 115,816,883 and divide it by 2:
115,816,883 ÷ 2 = 57,908,441.5
If the quotient is a whole number, then 2 and 57,908,441.5 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 | 115,816,883 | |
| -1 | -115,816,883 |
Now, we try dividing 115,816,883 by 3:
115,816,883 ÷ 3 = 38,605,627.6667
If the quotient is a whole number, then 3 and 38,605,627.6667 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 | 115,816,883 | |
| -1 | -115,816,883 |
Let's try dividing by 4:
115,816,883 ÷ 4 = 28,954,220.75
If the quotient is a whole number, then 4 and 28,954,220.75 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 | 115,816,883 | |
| -1 | 115,816,883 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 47 | 91 | 169 | 329 | 611 | 1,183 | 2,083 | 4,277 | 7,943 | 14,581 | 27,079 | 55,601 | 97,901 | 189,553 | 352,027 | 685,307 | 1,272,713 | 2,464,189 | 8,908,991 | 16,545,269 | 115,816,883 |
| -1 | -7 | -13 | -47 | -91 | -169 | -329 | -611 | -1,183 | -2,083 | -4,277 | -7,943 | -14,581 | -27,079 | -55,601 | -97,901 | -189,553 | -352,027 | -685,307 | -1,272,713 | -2,464,189 | -8,908,991 | -16,545,269 | -115,816,883 |
