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 110,811,115, 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 | 110,811,115 | |
| -1 | -110,811,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,811,115.
Example:
1 x 110,811,115 = 110,811,115
and
-1 x -110,811,115 = 110,811,115
Notice both answers equal 110,811,115
With that explanation out of the way, let's continue. Next, we take the number 110,811,115 and divide it by 2:
110,811,115 ÷ 2 = 55,405,557.5
If the quotient is a whole number, then 2 and 55,405,557.5 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 | 110,811,115 | |
| -1 | -110,811,115 |
Now, we try dividing 110,811,115 by 3:
110,811,115 ÷ 3 = 36,937,038.3333
If the quotient is a whole number, then 3 and 36,937,038.3333 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 | 110,811,115 | |
| -1 | -110,811,115 |
Let's try dividing by 4:
110,811,115 ÷ 4 = 27,702,778.75
If the quotient is a whole number, then 4 and 27,702,778.75 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 | 110,811,115 | |
| -1 | 110,811,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 571 | 1,049 | 2,855 | 5,245 | 21,127 | 38,813 | 105,635 | 194,065 | 598,979 | 2,994,895 | 22,162,223 | 110,811,115 |
| -1 | -5 | -37 | -185 | -571 | -1,049 | -2,855 | -5,245 | -21,127 | -38,813 | -105,635 | -194,065 | -598,979 | -2,994,895 | -22,162,223 | -110,811,115 |
