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 115,273,625, 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 | 115,273,625 | |
| -1 | -115,273,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,273,625.
Example:
1 x 115,273,625 = 115,273,625
and
-1 x -115,273,625 = 115,273,625
Notice both answers equal 115,273,625
With that explanation out of the way, let's continue. Next, we take the number 115,273,625 and divide it by 2:
115,273,625 ÷ 2 = 57,636,812.5
If the quotient is a whole number, then 2 and 57,636,812.5 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 | 115,273,625 | |
| -1 | -115,273,625 |
Now, we try dividing 115,273,625 by 3:
115,273,625 ÷ 3 = 38,424,541.6667
If the quotient is a whole number, then 3 and 38,424,541.6667 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 | 115,273,625 | |
| -1 | -115,273,625 |
Let's try dividing by 4:
115,273,625 ÷ 4 = 28,818,406.25
If the quotient is a whole number, then 4 and 28,818,406.25 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 | 115,273,625 | |
| -1 | 115,273,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 773 | 1,193 | 3,865 | 5,965 | 19,325 | 29,825 | 96,625 | 149,125 | 922,189 | 4,610,945 | 23,054,725 | 115,273,625 |
| -1 | -5 | -25 | -125 | -773 | -1,193 | -3,865 | -5,965 | -19,325 | -29,825 | -96,625 | -149,125 | -922,189 | -4,610,945 | -23,054,725 | -115,273,625 |
