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 115,542,305, 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 | 115,542,305 | |
| -1 | -115,542,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,542,305.
Example:
1 x 115,542,305 = 115,542,305
and
-1 x -115,542,305 = 115,542,305
Notice both answers equal 115,542,305
With that explanation out of the way, let's continue. Next, we take the number 115,542,305 and divide it by 2:
115,542,305 ÷ 2 = 57,771,152.5
If the quotient is a whole number, then 2 and 57,771,152.5 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 | 115,542,305 | |
| -1 | -115,542,305 |
Now, we try dividing 115,542,305 by 3:
115,542,305 ÷ 3 = 38,514,101.6667
If the quotient is a whole number, then 3 and 38,514,101.6667 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 | 115,542,305 | |
| -1 | -115,542,305 |
Let's try dividing by 4:
115,542,305 ÷ 4 = 28,885,576.25
If the quotient is a whole number, then 4 and 28,885,576.25 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 | 115,542,305 | |
| -1 | 115,542,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 41 | 185 | 205 | 1,517 | 7,585 | 15,233 | 76,165 | 563,621 | 624,553 | 2,818,105 | 3,122,765 | 23,108,461 | 115,542,305 |
| -1 | -5 | -37 | -41 | -185 | -205 | -1,517 | -7,585 | -15,233 | -76,165 | -563,621 | -624,553 | -2,818,105 | -3,122,765 | -23,108,461 | -115,542,305 |
