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 115,068,373, 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 | 115,068,373 | |
| -1 | -115,068,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,068,373.
Example:
1 x 115,068,373 = 115,068,373
and
-1 x -115,068,373 = 115,068,373
Notice both answers equal 115,068,373
With that explanation out of the way, let's continue. Next, we take the number 115,068,373 and divide it by 2:
115,068,373 ÷ 2 = 57,534,186.5
If the quotient is a whole number, then 2 and 57,534,186.5 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 | 115,068,373 | |
| -1 | -115,068,373 |
Now, we try dividing 115,068,373 by 3:
115,068,373 ÷ 3 = 38,356,124.3333
If the quotient is a whole number, then 3 and 38,356,124.3333 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 | 115,068,373 | |
| -1 | -115,068,373 |
Let's try dividing by 4:
115,068,373 ÷ 4 = 28,767,093.25
If the quotient is a whole number, then 4 and 28,767,093.25 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 | 115,068,373 | |
| -1 | 115,068,373 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 449 | 1,181 | 3,143 | 8,267 | 13,919 | 36,611 | 97,433 | 256,277 | 530,269 | 3,711,883 | 16,438,339 | 115,068,373 |
| -1 | -7 | -31 | -217 | -449 | -1,181 | -3,143 | -8,267 | -13,919 | -36,611 | -97,433 | -256,277 | -530,269 | -3,711,883 | -16,438,339 | -115,068,373 |
