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 23,111,099, 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 | 23,111,099 | |
| -1 | -23,111,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,111,099.
Example:
1 x 23,111,099 = 23,111,099
and
-1 x -23,111,099 = 23,111,099
Notice both answers equal 23,111,099
With that explanation out of the way, let's continue. Next, we take the number 23,111,099 and divide it by 2:
23,111,099 ÷ 2 = 11,555,549.5
If the quotient is a whole number, then 2 and 11,555,549.5 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 | 23,111,099 | |
| -1 | -23,111,099 |
Now, we try dividing 23,111,099 by 3:
23,111,099 ÷ 3 = 7,703,699.6667
If the quotient is a whole number, then 3 and 7,703,699.6667 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 | 23,111,099 | |
| -1 | -23,111,099 |
Let's try dividing by 4:
23,111,099 ÷ 4 = 5,777,774.75
If the quotient is a whole number, then 4 and 5,777,774.75 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 | 23,111,099 | |
| -1 | 23,111,099 |
If you did it right, you will end up with this table:
| 1 | 11 | 113 | 1,243 | 18,593 | 204,523 | 2,101,009 | 23,111,099 |
| -1 | -11 | -113 | -1,243 | -18,593 | -204,523 | -2,101,009 | -23,111,099 |
