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 115,134,227, 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 | 115,134,227 | |
| -1 | -115,134,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,134,227.
Example:
1 x 115,134,227 = 115,134,227
and
-1 x -115,134,227 = 115,134,227
Notice both answers equal 115,134,227
With that explanation out of the way, let's continue. Next, we take the number 115,134,227 and divide it by 2:
115,134,227 ÷ 2 = 57,567,113.5
If the quotient is a whole number, then 2 and 57,567,113.5 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 | 115,134,227 | |
| -1 | -115,134,227 |
Now, we try dividing 115,134,227 by 3:
115,134,227 ÷ 3 = 38,378,075.6667
If the quotient is a whole number, then 3 and 38,378,075.6667 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 | 115,134,227 | |
| -1 | -115,134,227 |
Let's try dividing by 4:
115,134,227 ÷ 4 = 28,783,556.75
If the quotient is a whole number, then 4 and 28,783,556.75 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 | 115,134,227 | |
| -1 | 115,134,227 |
If you did it right, you will end up with this table:
| 1 | 13 | 89 | 191 | 521 | 1,157 | 2,483 | 6,773 | 16,999 | 46,369 | 99,511 | 220,987 | 602,797 | 1,293,643 | 8,856,479 | 115,134,227 |
| -1 | -13 | -89 | -191 | -521 | -1,157 | -2,483 | -6,773 | -16,999 | -46,369 | -99,511 | -220,987 | -602,797 | -1,293,643 | -8,856,479 | -115,134,227 |
