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 111,023,099, 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 | 111,023,099 | |
| -1 | -111,023,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,023,099.
Example:
1 x 111,023,099 = 111,023,099
and
-1 x -111,023,099 = 111,023,099
Notice both answers equal 111,023,099
With that explanation out of the way, let's continue. Next, we take the number 111,023,099 and divide it by 2:
111,023,099 ÷ 2 = 55,511,549.5
If the quotient is a whole number, then 2 and 55,511,549.5 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 | 111,023,099 | |
| -1 | -111,023,099 |
Now, we try dividing 111,023,099 by 3:
111,023,099 ÷ 3 = 37,007,699.6667
If the quotient is a whole number, then 3 and 37,007,699.6667 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 | 111,023,099 | |
| -1 | -111,023,099 |
Let's try dividing by 4:
111,023,099 ÷ 4 = 27,755,774.75
If the quotient is a whole number, then 4 and 27,755,774.75 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 | 111,023,099 | |
| -1 | 111,023,099 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 209 | 479 | 1,109 | 5,269 | 9,101 | 12,199 | 21,071 | 100,111 | 231,781 | 531,211 | 5,843,321 | 10,093,009 | 111,023,099 |
| -1 | -11 | -19 | -209 | -479 | -1,109 | -5,269 | -9,101 | -12,199 | -21,071 | -100,111 | -231,781 | -531,211 | -5,843,321 | -10,093,009 | -111,023,099 |
