Show that....

Show that there are infinitely many prime numbers.........

I've some confusion in this proof...

We first assume that any number greater than 1 is either a prime or product of primes
fine

Again

we consider a number N = p1.p2................pn + 1 , why do we consider this N?....

maybe some of u will find it to be silly

Well if there is no such N then it means that there are infinitly many primes ... and in that case there will be nothing left to prove [1]

Wo why, N = p1.p2.............pn + 1 why this + 1
