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 115,443,251, 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 | 115,443,251 | |
| -1 | -115,443,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,443,251.
Example:
1 x 115,443,251 = 115,443,251
and
-1 x -115,443,251 = 115,443,251
Notice both answers equal 115,443,251
With that explanation out of the way, let's continue. Next, we take the number 115,443,251 and divide it by 2:
115,443,251 ÷ 2 = 57,721,625.5
If the quotient is a whole number, then 2 and 57,721,625.5 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 | 115,443,251 | |
| -1 | -115,443,251 |
Now, we try dividing 115,443,251 by 3:
115,443,251 ÷ 3 = 38,481,083.6667
If the quotient is a whole number, then 3 and 38,481,083.6667 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 | 115,443,251 | |
| -1 | -115,443,251 |
Let's try dividing by 4:
115,443,251 ÷ 4 = 28,860,812.75
If the quotient is a whole number, then 4 and 28,860,812.75 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 | 115,443,251 | |
| -1 | 115,443,251 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 229 | 1,603 | 2,519 | 6,547 | 17,633 | 45,829 | 72,017 | 504,119 | 1,499,263 | 10,494,841 | 16,491,893 | 115,443,251 |
| -1 | -7 | -11 | -77 | -229 | -1,603 | -2,519 | -6,547 | -17,633 | -45,829 | -72,017 | -504,119 | -1,499,263 | -10,494,841 | -16,491,893 | -115,443,251 |
