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 111,115,015, 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 | 111,115,015 | |
| -1 | -111,115,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,115,015.
Example:
1 x 111,115,015 = 111,115,015
and
-1 x -111,115,015 = 111,115,015
Notice both answers equal 111,115,015
With that explanation out of the way, let's continue. Next, we take the number 111,115,015 and divide it by 2:
111,115,015 ÷ 2 = 55,557,507.5
If the quotient is a whole number, then 2 and 55,557,507.5 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 | 111,115,015 | |
| -1 | -111,115,015 |
Now, we try dividing 111,115,015 by 3:
111,115,015 ÷ 3 = 37,038,338.3333
If the quotient is a whole number, then 3 and 37,038,338.3333 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 | 111,115,015 | |
| -1 | -111,115,015 |
Let's try dividing by 4:
111,115,015 ÷ 4 = 27,778,753.75
If the quotient is a whole number, then 4 and 27,778,753.75 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 | 111,115,015 | |
| -1 | 111,115,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 829 | 2,437 | 4,145 | 9,119 | 12,185 | 26,807 | 45,595 | 134,035 | 2,020,273 | 10,101,365 | 22,223,003 | 111,115,015 |
| -1 | -5 | -11 | -55 | -829 | -2,437 | -4,145 | -9,119 | -12,185 | -26,807 | -45,595 | -134,035 | -2,020,273 | -10,101,365 | -22,223,003 | -111,115,015 |
