Challenge: fortunate number
a fortunate number (NOT to be confused with lucky number!!!) x>n is the smallest natural number that, if added to the product of all prime numbers from 1 to n, gives another prime number. example: assuming n is 17, the product of prime numbers from 1 to 17 is 510510. if we add 18 to 510510 we don't have a prime number (510528 is not prime), so we skip 18 and go to 19 that (surprise!!!) is a fortunate number because 510529 is prime! task: write a code that, once user inputs a natural integer n, finds the first fortunate number after n! enjoy :)

@baptiste thank you for answering 😊 just tried your code with the provided example, but the fortunate number is non 510529, it's 19 ad it's the smallest integer after 17 ti create a prime if added to product of all prime numbers till 17 🙃 it should be an easy fix anyway 😊

after n, or after n! ? That is a huge difference, actually.
