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 115,437,005, 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 | 115,437,005 | |
| -1 | -115,437,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,437,005.
Example:
1 x 115,437,005 = 115,437,005
and
-1 x -115,437,005 = 115,437,005
Notice both answers equal 115,437,005
With that explanation out of the way, let's continue. Next, we take the number 115,437,005 and divide it by 2:
115,437,005 ÷ 2 = 57,718,502.5
If the quotient is a whole number, then 2 and 57,718,502.5 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 | 115,437,005 | |
| -1 | -115,437,005 |
Now, we try dividing 115,437,005 by 3:
115,437,005 ÷ 3 = 38,479,001.6667
If the quotient is a whole number, then 3 and 38,479,001.6667 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 | 115,437,005 | |
| -1 | -115,437,005 |
Let's try dividing by 4:
115,437,005 ÷ 4 = 28,859,251.25
If the quotient is a whole number, then 4 and 28,859,251.25 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 | 115,437,005 | |
| -1 | 115,437,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 149 | 445 | 745 | 1,741 | 8,705 | 13,261 | 66,305 | 154,949 | 259,409 | 774,745 | 1,297,045 | 23,087,401 | 115,437,005 |
| -1 | -5 | -89 | -149 | -445 | -745 | -1,741 | -8,705 | -13,261 | -66,305 | -154,949 | -259,409 | -774,745 | -1,297,045 | -23,087,401 | -115,437,005 |
