Why are prime numbers important in real life? What practical use are prime numbers?
Ask periodical cidacas why they use prime numbers for the cycle length.
Primes are used in several routines in information technology, such as public-key cryptography, which makes use of properties such as the difficulty of factoring large numbers into their prime factors. Prime numbers give rise to various generalizations in other mathematical domains, mainly algebra, such as prime elements and prime ideals.

Definitely a real life application.
Isn't math real life?
For a mathematician it certainly is!
Interesting Borek. I had to investigate:
Poor Hardy! He went to his grave proud of the uselessness of number theory.
Strange that a discipline studied for millennia suddenly became useful only a couple of decades ago.
true, but primes also became important with the invention and the use of computers ...
