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 110,540,315, 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 | 110,540,315 | |
| -1 | -110,540,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,540,315.
Example:
1 x 110,540,315 = 110,540,315
and
-1 x -110,540,315 = 110,540,315
Notice both answers equal 110,540,315
With that explanation out of the way, let's continue. Next, we take the number 110,540,315 and divide it by 2:
110,540,315 ÷ 2 = 55,270,157.5
If the quotient is a whole number, then 2 and 55,270,157.5 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 | 110,540,315 | |
| -1 | -110,540,315 |
Now, we try dividing 110,540,315 by 3:
110,540,315 ÷ 3 = 36,846,771.6667
If the quotient is a whole number, then 3 and 36,846,771.6667 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 | 110,540,315 | |
| -1 | -110,540,315 |
Let's try dividing by 4:
110,540,315 ÷ 4 = 27,635,078.75
If the quotient is a whole number, then 4 and 27,635,078.75 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 | 110,540,315 | |
| -1 | 110,540,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 43 | 145 | 215 | 1,247 | 6,235 | 17,729 | 88,645 | 514,141 | 762,347 | 2,570,705 | 3,811,735 | 22,108,063 | 110,540,315 |
| -1 | -5 | -29 | -43 | -145 | -215 | -1,247 | -6,235 | -17,729 | -88,645 | -514,141 | -762,347 | -2,570,705 | -3,811,735 | -22,108,063 | -110,540,315 |
