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 115,809,001, 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 | 115,809,001 | |
| -1 | -115,809,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,809,001.
Example:
1 x 115,809,001 = 115,809,001
and
-1 x -115,809,001 = 115,809,001
Notice both answers equal 115,809,001
With that explanation out of the way, let's continue. Next, we take the number 115,809,001 and divide it by 2:
115,809,001 ÷ 2 = 57,904,500.5
If the quotient is a whole number, then 2 and 57,904,500.5 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 | 115,809,001 | |
| -1 | -115,809,001 |
Now, we try dividing 115,809,001 by 3:
115,809,001 ÷ 3 = 38,603,000.3333
If the quotient is a whole number, then 3 and 38,603,000.3333 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 | 115,809,001 | |
| -1 | -115,809,001 |
Let's try dividing by 4:
115,809,001 ÷ 4 = 28,952,250.25
If the quotient is a whole number, then 4 and 28,952,250.25 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 | 115,809,001 | |
| -1 | 115,809,001 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 49 | 77 | 259 | 407 | 539 | 1,813 | 2,849 | 5,807 | 19,943 | 40,649 | 63,877 | 214,859 | 284,543 | 447,139 | 1,504,013 | 2,363,449 | 3,129,973 | 10,528,091 | 16,544,143 | 115,809,001 |
| -1 | -7 | -11 | -37 | -49 | -77 | -259 | -407 | -539 | -1,813 | -2,849 | -5,807 | -19,943 | -40,649 | -63,877 | -214,859 | -284,543 | -447,139 | -1,504,013 | -2,363,449 | -3,129,973 | -10,528,091 | -16,544,143 | -115,809,001 |
