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 11,201,255, 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 | 11,201,255 | |
| -1 | -11,201,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,201,255.
Example:
1 x 11,201,255 = 11,201,255
and
-1 x -11,201,255 = 11,201,255
Notice both answers equal 11,201,255
With that explanation out of the way, let's continue. Next, we take the number 11,201,255 and divide it by 2:
11,201,255 ÷ 2 = 5,600,627.5
If the quotient is a whole number, then 2 and 5,600,627.5 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 | 11,201,255 | |
| -1 | -11,201,255 |
Now, we try dividing 11,201,255 by 3:
11,201,255 ÷ 3 = 3,733,751.6667
If the quotient is a whole number, then 3 and 3,733,751.6667 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 | 11,201,255 | |
| -1 | -11,201,255 |
Let's try dividing by 4:
11,201,255 ÷ 4 = 2,800,313.75
If the quotient is a whole number, then 4 and 2,800,313.75 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 | 11,201,255 | |
| -1 | 11,201,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 389 | 443 | 1,945 | 2,215 | 5,057 | 5,759 | 25,285 | 28,795 | 172,327 | 861,635 | 2,240,251 | 11,201,255 |
| -1 | -5 | -13 | -65 | -389 | -443 | -1,945 | -2,215 | -5,057 | -5,759 | -25,285 | -28,795 | -172,327 | -861,635 | -2,240,251 | -11,201,255 |
