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 115,882,865, 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 | 115,882,865 | |
| -1 | -115,882,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,882,865.
Example:
1 x 115,882,865 = 115,882,865
and
-1 x -115,882,865 = 115,882,865
Notice both answers equal 115,882,865
With that explanation out of the way, let's continue. Next, we take the number 115,882,865 and divide it by 2:
115,882,865 ÷ 2 = 57,941,432.5
If the quotient is a whole number, then 2 and 57,941,432.5 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 | 115,882,865 | |
| -1 | -115,882,865 |
Now, we try dividing 115,882,865 by 3:
115,882,865 ÷ 3 = 38,627,621.6667
If the quotient is a whole number, then 3 and 38,627,621.6667 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 | 115,882,865 | |
| -1 | -115,882,865 |
Let's try dividing by 4:
115,882,865 ÷ 4 = 28,970,716.25
If the quotient is a whole number, then 4 and 28,970,716.25 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 | 115,882,865 | |
| -1 | 115,882,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 67 | 335 | 469 | 2,345 | 49,417 | 247,085 | 345,919 | 1,729,595 | 3,310,939 | 16,554,695 | 23,176,573 | 115,882,865 |
| -1 | -5 | -7 | -35 | -67 | -335 | -469 | -2,345 | -49,417 | -247,085 | -345,919 | -1,729,595 | -3,310,939 | -16,554,695 | -23,176,573 | -115,882,865 |
