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 115,431,095, 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 | 115,431,095 | |
| -1 | -115,431,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,431,095.
Example:
1 x 115,431,095 = 115,431,095
and
-1 x -115,431,095 = 115,431,095
Notice both answers equal 115,431,095
With that explanation out of the way, let's continue. Next, we take the number 115,431,095 and divide it by 2:
115,431,095 ÷ 2 = 57,715,547.5
If the quotient is a whole number, then 2 and 57,715,547.5 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 | 115,431,095 | |
| -1 | -115,431,095 |
Now, we try dividing 115,431,095 by 3:
115,431,095 ÷ 3 = 38,477,031.6667
If the quotient is a whole number, then 3 and 38,477,031.6667 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 | 115,431,095 | |
| -1 | -115,431,095 |
Let's try dividing by 4:
115,431,095 ÷ 4 = 28,857,773.75
If the quotient is a whole number, then 4 and 28,857,773.75 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 | 115,431,095 | |
| -1 | 115,431,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 271 | 1,355 | 3,523 | 6,553 | 17,615 | 32,765 | 85,189 | 425,945 | 1,775,863 | 8,879,315 | 23,086,219 | 115,431,095 |
| -1 | -5 | -13 | -65 | -271 | -1,355 | -3,523 | -6,553 | -17,615 | -32,765 | -85,189 | -425,945 | -1,775,863 | -8,879,315 | -23,086,219 | -115,431,095 |
