解题报告:求多个数的最小公倍数,其实还是一样,只需要一个一个求就行了,先将答案初始化为1,然后让这个数依次跟其他的每个数进行求最小公倍数,最后求出来的就是所有的数的最小公倍数.也就是多次GCD． #include<cstdio> #include<iostream> #include<cstring> using namespace std; typedef __int64 INT; INT GCD(INT a,INT b) { ? b:GCD(b,a%b); } in…

求一组数据的最小公倍数. 先求公约数在求公倍数.利用公倍数,连续求全部数的公倍数就能够了. #include <stdio.h> int GCD(int a, int b) { return b? GCD(b, a%b) : a; } inline int LCM(int a, int b) { return a / GCD(a, b) * b; } int main() { int T, m, a, b; scanf("%d", &T); while (T--)…
