> any non prime number will atleast have 3 factors (including 1, it's square root, and itself).
>>sqrt(21) = 4.582575...
>> not a factor of 21. A factor has to be an integer.
so what i said was wrong ? i guess not..
we ALWAYS consider factors as integers... otherwise, we
can come up with countless factors for every single number
(think about how many decimal places you can consider...
the permutations are endless... )
have fun
