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 23,231,135, 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 | 23,231,135 | |
| -1 | -23,231,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,231,135.
Example:
1 x 23,231,135 = 23,231,135
and
-1 x -23,231,135 = 23,231,135
Notice both answers equal 23,231,135
With that explanation out of the way, let's continue. Next, we take the number 23,231,135 and divide it by 2:
23,231,135 ÷ 2 = 11,615,567.5
If the quotient is a whole number, then 2 and 11,615,567.5 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 | 23,231,135 | |
| -1 | -23,231,135 |
Now, we try dividing 23,231,135 by 3:
23,231,135 ÷ 3 = 7,743,711.6667
If the quotient is a whole number, then 3 and 7,743,711.6667 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 | 23,231,135 | |
| -1 | -23,231,135 |
Let's try dividing by 4:
23,231,135 ÷ 4 = 5,807,783.75
If the quotient is a whole number, then 4 and 5,807,783.75 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 | 23,231,135 | |
| -1 | 23,231,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 103 | 395 | 515 | 571 | 2,855 | 8,137 | 40,685 | 45,109 | 58,813 | 225,545 | 294,065 | 4,646,227 | 23,231,135 |
| -1 | -5 | -79 | -103 | -395 | -515 | -571 | -2,855 | -8,137 | -40,685 | -45,109 | -58,813 | -225,545 | -294,065 | -4,646,227 | -23,231,135 |
