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 115,247,483, 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 | 115,247,483 | |
| -1 | -115,247,483 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,247,483.
Example:
1 x 115,247,483 = 115,247,483
and
-1 x -115,247,483 = 115,247,483
Notice both answers equal 115,247,483
With that explanation out of the way, let's continue. Next, we take the number 115,247,483 and divide it by 2:
115,247,483 ÷ 2 = 57,623,741.5
If the quotient is a whole number, then 2 and 57,623,741.5 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 | 115,247,483 | |
| -1 | -115,247,483 |
Now, we try dividing 115,247,483 by 3:
115,247,483 ÷ 3 = 38,415,827.6667
If the quotient is a whole number, then 3 and 38,415,827.6667 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 | 115,247,483 | |
| -1 | -115,247,483 |
Let's try dividing by 4:
115,247,483 ÷ 4 = 28,811,870.75
If the quotient is a whole number, then 4 and 28,811,870.75 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 | 115,247,483 | |
| -1 | 115,247,483 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 61 | 247 | 793 | 1,159 | 7,649 | 15,067 | 99,437 | 145,331 | 466,589 | 1,889,303 | 6,065,657 | 8,865,191 | 115,247,483 |
| -1 | -13 | -19 | -61 | -247 | -793 | -1,159 | -7,649 | -15,067 | -99,437 | -145,331 | -466,589 | -1,889,303 | -6,065,657 | -8,865,191 | -115,247,483 |
