This is why: The gcd(a,d) is 23⋅3 and the gcd of (c,d) is 2⋅33. However, the gcd of (b,c)=22⋅32 (meaning both are divisible by 36). Therefore, a is only divisible by 31 (and no higher power of 3), while d is divisible by only 反馈 收藏 ...
Notice that gcd(a,b,c,d)=gcd(gcd(a,b),gcd(b,c),gcd(c,d))=gcd(24,36,54)=6, so gcd(d,a) must be a multiple of 6. The only answer choice that gives a value between 70 and 100 when multiplied by 6 is (D) 13.结果一 题目 Let a,b,c and d be positive integers suc...
GCD, operating at the system level, can better accommodate the needs of all running applications, matching them to the available system resources in a balanced fashion. 翻译: GCD运行在系统级,可以更好地满足所有正在运行的应用程序的需求,以平衡的方式将它们与可用的系统资源进行匹配。
