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 22,459,255, 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 | 22,459,255 | |
| -1 | -22,459,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,459,255.
Example:
1 x 22,459,255 = 22,459,255
and
-1 x -22,459,255 = 22,459,255
Notice both answers equal 22,459,255
With that explanation out of the way, let's continue. Next, we take the number 22,459,255 and divide it by 2:
22,459,255 ÷ 2 = 11,229,627.5
If the quotient is a whole number, then 2 and 11,229,627.5 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 | 22,459,255 | |
| -1 | -22,459,255 |
Now, we try dividing 22,459,255 by 3:
22,459,255 ÷ 3 = 7,486,418.3333
If the quotient is a whole number, then 3 and 7,486,418.3333 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 | 22,459,255 | |
| -1 | -22,459,255 |
Let's try dividing by 4:
22,459,255 ÷ 4 = 5,614,813.75
If the quotient is a whole number, then 4 and 5,614,813.75 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 | 22,459,255 | |
| -1 | 22,459,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 3,797 | 5,915 | 18,985 | 26,579 | 49,361 | 132,895 | 246,805 | 345,527 | 641,693 | 1,727,635 | 3,208,465 | 4,491,851 | 22,459,255 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -3,797 | -5,915 | -18,985 | -26,579 | -49,361 | -132,895 | -246,805 | -345,527 | -641,693 | -1,727,635 | -3,208,465 | -4,491,851 | -22,459,255 |
