Note that all solutions (which passed the limited test suite with small size) involving only pair-wise gcd calculations are indeed incorrect. Those solutions include the following ones: 1) min(gcd(a,min(a))); 2) min(gcd(a(1), a)); 3) min(min(bsxfun(@gcd,a,a.'))); To eliminate these incorrect solutions, please simply add a test case with a = [21 15 35].
