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 115,050,871, 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 | 115,050,871 | |
| -1 | -115,050,871 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,050,871.
Example:
1 x 115,050,871 = 115,050,871
and
-1 x -115,050,871 = 115,050,871
Notice both answers equal 115,050,871
With that explanation out of the way, let's continue. Next, we take the number 115,050,871 and divide it by 2:
115,050,871 ÷ 2 = 57,525,435.5
If the quotient is a whole number, then 2 and 57,525,435.5 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 | 115,050,871 | |
| -1 | -115,050,871 |
Now, we try dividing 115,050,871 by 3:
115,050,871 ÷ 3 = 38,350,290.3333
If the quotient is a whole number, then 3 and 38,350,290.3333 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 | 115,050,871 | |
| -1 | -115,050,871 |
Let's try dividing by 4:
115,050,871 ÷ 4 = 28,762,717.75
If the quotient is a whole number, then 4 and 28,762,717.75 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 | 115,050,871 | |
| -1 | 115,050,871 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 37 | 247 | 481 | 703 | 9,139 | 12,589 | 163,657 | 239,191 | 465,793 | 3,109,483 | 6,055,309 | 8,850,067 | 115,050,871 |
| -1 | -13 | -19 | -37 | -247 | -481 | -703 | -9,139 | -12,589 | -163,657 | -239,191 | -465,793 | -3,109,483 | -6,055,309 | -8,850,067 | -115,050,871 |
