WebSince the primes vector size is ~1200 (number of primes in [1,10000]), won't it take time to iterate through all these primes, for every element (n=30000, so 30000*1200 in the worst case), to get its vector of prime divisors? I am not aware of any other optimized approach here to get the vector. WebBy definition, a pair of integers a, b are coprime if they have only trivial common factors, i.e. g c d ( a, b) = 1, i.e. c a, b ⇒ c 1.
