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 116,073,515, 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 | 116,073,515 | |
| -1 | -116,073,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,073,515.
Example:
1 x 116,073,515 = 116,073,515
and
-1 x -116,073,515 = 116,073,515
Notice both answers equal 116,073,515
With that explanation out of the way, let's continue. Next, we take the number 116,073,515 and divide it by 2:
116,073,515 ÷ 2 = 58,036,757.5
If the quotient is a whole number, then 2 and 58,036,757.5 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 | 116,073,515 | |
| -1 | -116,073,515 |
Now, we try dividing 116,073,515 by 3:
116,073,515 ÷ 3 = 38,691,171.6667
If the quotient is a whole number, then 3 and 38,691,171.6667 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 | 116,073,515 | |
| -1 | -116,073,515 |
Let's try dividing by 4:
116,073,515 ÷ 4 = 29,018,378.75
If the quotient is a whole number, then 4 and 29,018,378.75 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 | 116,073,515 | |
| -1 | 116,073,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 79 | 145 | 395 | 2,291 | 10,133 | 11,455 | 50,665 | 293,857 | 800,507 | 1,469,285 | 4,002,535 | 23,214,703 | 116,073,515 |
| -1 | -5 | -29 | -79 | -145 | -395 | -2,291 | -10,133 | -11,455 | -50,665 | -293,857 | -800,507 | -1,469,285 | -4,002,535 | -23,214,703 | -116,073,515 |
