It is a waste of time !
Just today i saw in the home page of CE, that the largest prime number is 17 million digits strong.(or so i read).
But until today the largest prime number was something smaller.
And most probably in the future the new "largest" prime will be discovered which will have more than 17 million digits.
but then don't you guys think that this never ending quest of finding the largest prime is just a waste of time.
I will tell you what the largest prime is, it is INFINITY !. And this is also the largest composite number as well.
