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 115,120,313, 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 | 115,120,313 | |
| -1 | -115,120,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,120,313.
Example:
1 x 115,120,313 = 115,120,313
and
-1 x -115,120,313 = 115,120,313
Notice both answers equal 115,120,313
With that explanation out of the way, let's continue. Next, we take the number 115,120,313 and divide it by 2:
115,120,313 ÷ 2 = 57,560,156.5
If the quotient is a whole number, then 2 and 57,560,156.5 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 | 115,120,313 | |
| -1 | -115,120,313 |
Now, we try dividing 115,120,313 by 3:
115,120,313 ÷ 3 = 38,373,437.6667
If the quotient is a whole number, then 3 and 38,373,437.6667 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 | 115,120,313 | |
| -1 | -115,120,313 |
Let's try dividing by 4:
115,120,313 ÷ 4 = 28,780,078.25
If the quotient is a whole number, then 4 and 28,780,078.25 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 | 115,120,313 | |
| -1 | 115,120,313 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 65,003 | 455,021 | 715,033 | 1,495,069 | 5,005,231 | 10,465,483 | 16,445,759 | 115,120,313 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -65,003 | -455,021 | -715,033 | -1,495,069 | -5,005,231 | -10,465,483 | -16,445,759 | -115,120,313 |
