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 115,242,035, 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 | 115,242,035 | |
| -1 | -115,242,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,242,035.
Example:
1 x 115,242,035 = 115,242,035
and
-1 x -115,242,035 = 115,242,035
Notice both answers equal 115,242,035
With that explanation out of the way, let's continue. Next, we take the number 115,242,035 and divide it by 2:
115,242,035 ÷ 2 = 57,621,017.5
If the quotient is a whole number, then 2 and 57,621,017.5 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 | 115,242,035 | |
| -1 | -115,242,035 |
Now, we try dividing 115,242,035 by 3:
115,242,035 ÷ 3 = 38,414,011.6667
If the quotient is a whole number, then 3 and 38,414,011.6667 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 | 115,242,035 | |
| -1 | -115,242,035 |
Let's try dividing by 4:
115,242,035 ÷ 4 = 28,810,508.75
If the quotient is a whole number, then 4 and 28,810,508.75 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 | 115,242,035 | |
| -1 | 115,242,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 761 | 977 | 3,805 | 4,885 | 23,591 | 30,287 | 117,955 | 151,435 | 743,497 | 3,717,485 | 23,048,407 | 115,242,035 |
| -1 | -5 | -31 | -155 | -761 | -977 | -3,805 | -4,885 | -23,591 | -30,287 | -117,955 | -151,435 | -743,497 | -3,717,485 | -23,048,407 | -115,242,035 |
