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 115,340,303, 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 | 115,340,303 | |
| -1 | -115,340,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,340,303.
Example:
1 x 115,340,303 = 115,340,303
and
-1 x -115,340,303 = 115,340,303
Notice both answers equal 115,340,303
With that explanation out of the way, let's continue. Next, we take the number 115,340,303 and divide it by 2:
115,340,303 ÷ 2 = 57,670,151.5
If the quotient is a whole number, then 2 and 57,670,151.5 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 | 115,340,303 | |
| -1 | -115,340,303 |
Now, we try dividing 115,340,303 by 3:
115,340,303 ÷ 3 = 38,446,767.6667
If the quotient is a whole number, then 3 and 38,446,767.6667 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 | 115,340,303 | |
| -1 | -115,340,303 |
Let's try dividing by 4:
115,340,303 ÷ 4 = 28,835,075.75
If the quotient is a whole number, then 4 and 28,835,075.75 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 | 115,340,303 | |
| -1 | 115,340,303 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 169 | 611 | 1,117 | 2,197 | 7,943 | 14,521 | 52,499 | 103,259 | 188,773 | 682,487 | 2,454,049 | 8,872,331 | 115,340,303 |
| -1 | -13 | -47 | -169 | -611 | -1,117 | -2,197 | -7,943 | -14,521 | -52,499 | -103,259 | -188,773 | -682,487 | -2,454,049 | -8,872,331 | -115,340,303 |
