SpletPrimes are simple to define yet hard to classify. 1.6. Euclid’s proof of the infinitude of primes Suppose that p 1;:::;p k is a finite list of prime numbers. It suffices to show that we can always find another prime not on our list. Let m Dp 1 p k C1: How to conclude the proof? Informal. Since m > 1, it must be divisible by some prime number ... SpletThe inner loop checks if the current integer (i) is divisible by any integer between 2 and itself (represented by j). If i is not divisible by any integer between 2 and itself, then it is a prime number and is added to the primes string variable.
