题目描述 正整数A和正整数B 的最小公倍数是指 能被A和B整除的最小的正整数值,设计一个算法,求输入A和B的最小公倍数. 输入描述:输入两个正整数A和B. 输出描述:输出A和B的最小公倍数. 输入例子: 5 7 输出例子: 35 思路:两个数的最小公倍数等于两个数的乘积除以最大公约数 最大公约数:分解质因数,找出其中相同的质因数,再将它们相乘,就得到了最大公约数,如果两数的质因数中,没有一个是相同的,那么它们的最大公约数就是1 ps 第二个方法太智障了  hold package huawei2…

Problem Description The least common multiple (LCM) of a set of positive integers is the smallest positive integer which is divisible by all the numbers in the set. For example, the LCM of 5, 7 and 15 is 105. Input Input will consist of multiple prob…

太简单了...题目都不想贴了 //算n个数的最小公倍数 #include<cstdio> #include<cstring> #include<algorithm> using namespace std; int gcd(int a, int b) { ?a:gcd(b,a%b); } int lcm(int a, int b) { return a/gcd(a,b)*b; } int main() { int T; scanf("%d",&…

也称欧几里得算法 原理: gcd(a,b)=gcd(b,a mod b) 边界条件为 gcd(a,0)=a; 其中mod 为求余 故辗转相除法可简单的表示为: int gcd(int a, int b) { return b ==0? a:gcd( b, a% b); } 简洁而优雅. 例如:HDU 2028 Lowest Common Multiple Plus求n个数的最小公倍数. 最小公倍数=两数之积  /  最大公约数 这里防止中间过程溢出,先除以最大公约数,然后在求积. #includ…
