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 115,137,625, 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 | 115,137,625 | |
| -1 | -115,137,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,137,625.
Example:
1 x 115,137,625 = 115,137,625
and
-1 x -115,137,625 = 115,137,625
Notice both answers equal 115,137,625
With that explanation out of the way, let's continue. Next, we take the number 115,137,625 and divide it by 2:
115,137,625 ÷ 2 = 57,568,812.5
If the quotient is a whole number, then 2 and 57,568,812.5 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 | 115,137,625 | |
| -1 | -115,137,625 |
Now, we try dividing 115,137,625 by 3:
115,137,625 ÷ 3 = 38,379,208.3333
If the quotient is a whole number, then 3 and 38,379,208.3333 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 | 115,137,625 | |
| -1 | -115,137,625 |
Let's try dividing by 4:
115,137,625 ÷ 4 = 28,784,406.25
If the quotient is a whole number, then 4 and 28,784,406.25 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 | 115,137,625 | |
| -1 | 115,137,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 125 | 475 | 2,375 | 48,479 | 242,395 | 921,101 | 1,211,975 | 4,605,505 | 6,059,875 | 23,027,525 | 115,137,625 |
| -1 | -5 | -19 | -25 | -95 | -125 | -475 | -2,375 | -48,479 | -242,395 | -921,101 | -1,211,975 | -4,605,505 | -6,059,875 | -23,027,525 | -115,137,625 |
