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 23,311,255, 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 | 23,311,255 | |
| -1 | -23,311,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,311,255.
Example:
1 x 23,311,255 = 23,311,255
and
-1 x -23,311,255 = 23,311,255
Notice both answers equal 23,311,255
With that explanation out of the way, let's continue. Next, we take the number 23,311,255 and divide it by 2:
23,311,255 ÷ 2 = 11,655,627.5
If the quotient is a whole number, then 2 and 11,655,627.5 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 | 23,311,255 | |
| -1 | -23,311,255 |
Now, we try dividing 23,311,255 by 3:
23,311,255 ÷ 3 = 7,770,418.3333
If the quotient is a whole number, then 3 and 7,770,418.3333 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 | 23,311,255 | |
| -1 | -23,311,255 |
Let's try dividing by 4:
23,311,255 ÷ 4 = 5,827,813.75
If the quotient is a whole number, then 4 and 5,827,813.75 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 | 23,311,255 | |
| -1 | 23,311,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 121 | 265 | 583 | 605 | 727 | 2,915 | 3,635 | 6,413 | 7,997 | 32,065 | 38,531 | 39,985 | 87,967 | 192,655 | 423,841 | 439,835 | 2,119,205 | 4,662,251 | 23,311,255 |
| -1 | -5 | -11 | -53 | -55 | -121 | -265 | -583 | -605 | -727 | -2,915 | -3,635 | -6,413 | -7,997 | -32,065 | -38,531 | -39,985 | -87,967 | -192,655 | -423,841 | -439,835 | -2,119,205 | -4,662,251 | -23,311,255 |
