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 116,241,665, 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 | 116,241,665 | |
| -1 | -116,241,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,241,665.
Example:
1 x 116,241,665 = 116,241,665
and
-1 x -116,241,665 = 116,241,665
Notice both answers equal 116,241,665
With that explanation out of the way, let's continue. Next, we take the number 116,241,665 and divide it by 2:
116,241,665 ÷ 2 = 58,120,832.5
If the quotient is a whole number, then 2 and 58,120,832.5 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 | 116,241,665 | |
| -1 | -116,241,665 |
Now, we try dividing 116,241,665 by 3:
116,241,665 ÷ 3 = 38,747,221.6667
If the quotient is a whole number, then 3 and 38,747,221.6667 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 | 116,241,665 | |
| -1 | -116,241,665 |
Let's try dividing by 4:
116,241,665 ÷ 4 = 29,060,416.25
If the quotient is a whole number, then 4 and 29,060,416.25 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 | 116,241,665 | |
| -1 | 116,241,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 277 | 1,385 | 4,709 | 4,937 | 23,545 | 24,685 | 83,929 | 419,645 | 1,367,549 | 6,837,745 | 23,248,333 | 116,241,665 |
| -1 | -5 | -17 | -85 | -277 | -1,385 | -4,709 | -4,937 | -23,545 | -24,685 | -83,929 | -419,645 | -1,367,549 | -6,837,745 | -23,248,333 | -116,241,665 |
