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 115,073,705, 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 | 115,073,705 | |
| -1 | -115,073,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,073,705.
Example:
1 x 115,073,705 = 115,073,705
and
-1 x -115,073,705 = 115,073,705
Notice both answers equal 115,073,705
With that explanation out of the way, let's continue. Next, we take the number 115,073,705 and divide it by 2:
115,073,705 ÷ 2 = 57,536,852.5
If the quotient is a whole number, then 2 and 57,536,852.5 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 | 115,073,705 | |
| -1 | -115,073,705 |
Now, we try dividing 115,073,705 by 3:
115,073,705 ÷ 3 = 38,357,901.6667
If the quotient is a whole number, then 3 and 38,357,901.6667 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 | 115,073,705 | |
| -1 | -115,073,705 |
Let's try dividing by 4:
115,073,705 ÷ 4 = 28,768,426.25
If the quotient is a whole number, then 4 and 28,768,426.25 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 | 115,073,705 | |
| -1 | 115,073,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 337 | 1,685 | 2,203 | 10,447 | 11,015 | 52,235 | 68,293 | 341,465 | 742,411 | 3,712,055 | 23,014,741 | 115,073,705 |
| -1 | -5 | -31 | -155 | -337 | -1,685 | -2,203 | -10,447 | -11,015 | -52,235 | -68,293 | -341,465 | -742,411 | -3,712,055 | -23,014,741 | -115,073,705 |
