Choose k elements fromff an array so that the GCD is maximise.
Choose k elements from an array so that their GCD is maximise.
Constraints: N <= 3000 K <= N; K <= 100 Ai <= 10^10 (ten to the power of 10) I tried an algorithm of enumerating all divisors of ai and find the largest divisors that exists in >= k elements but it TLE. Can somebody help? Thanks in advance.
