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 12,554,255, 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 | 12,554,255 | |
| -1 | -12,554,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,554,255.
Example:
1 x 12,554,255 = 12,554,255
and
-1 x -12,554,255 = 12,554,255
Notice both answers equal 12,554,255
With that explanation out of the way, let's continue. Next, we take the number 12,554,255 and divide it by 2:
12,554,255 ÷ 2 = 6,277,127.5
If the quotient is a whole number, then 2 and 6,277,127.5 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 | 12,554,255 | |
| -1 | -12,554,255 |
Now, we try dividing 12,554,255 by 3:
12,554,255 ÷ 3 = 4,184,751.6667
If the quotient is a whole number, then 3 and 4,184,751.6667 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 | 12,554,255 | |
| -1 | -12,554,255 |
Let's try dividing by 4:
12,554,255 ÷ 4 = 3,138,563.75
If the quotient is a whole number, then 4 and 3,138,563.75 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 | 12,554,255 | |
| -1 | 12,554,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 409 | 877 | 2,045 | 2,863 | 4,385 | 6,139 | 14,315 | 30,695 | 358,693 | 1,793,465 | 2,510,851 | 12,554,255 |
| -1 | -5 | -7 | -35 | -409 | -877 | -2,045 | -2,863 | -4,385 | -6,139 | -14,315 | -30,695 | -358,693 | -1,793,465 | -2,510,851 | -12,554,255 |
