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 115,551,535, 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 | 115,551,535 | |
| -1 | -115,551,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,551,535.
Example:
1 x 115,551,535 = 115,551,535
and
-1 x -115,551,535 = 115,551,535
Notice both answers equal 115,551,535
With that explanation out of the way, let's continue. Next, we take the number 115,551,535 and divide it by 2:
115,551,535 ÷ 2 = 57,775,767.5
If the quotient is a whole number, then 2 and 57,775,767.5 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 | 115,551,535 | |
| -1 | -115,551,535 |
Now, we try dividing 115,551,535 by 3:
115,551,535 ÷ 3 = 38,517,178.3333
If the quotient is a whole number, then 3 and 38,517,178.3333 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 | 115,551,535 | |
| -1 | -115,551,535 |
Let's try dividing by 4:
115,551,535 ÷ 4 = 28,887,883.75
If the quotient is a whole number, then 4 and 28,887,883.75 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 | 115,551,535 | |
| -1 | 115,551,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 215 | 473 | 2,365 | 48,859 | 244,295 | 537,449 | 2,100,937 | 2,687,245 | 10,504,685 | 23,110,307 | 115,551,535 |
| -1 | -5 | -11 | -43 | -55 | -215 | -473 | -2,365 | -48,859 | -244,295 | -537,449 | -2,100,937 | -2,687,245 | -10,504,685 | -23,110,307 | -115,551,535 |
