Problem Description求n个数的最小公倍数。
Input输入包含多个测试实例,每个测试实例的开始是一个正整数n,然后是n个正整数。
Output为每组测试数据输出它们的最小公倍数,每个测试实例的输出占一行。你可以假设最后的输出是一个32位的整数。
Sample Input2 4 6 3 2 5 7
Sample Output12 70

正常的水题吧。
先用简单的辗转相除法求出最大公约数,再求出最小公倍数。
注意需要使用unsigned才可AC。
#include <iostream> using namespace std; unsigned getcount(unsigned a, unsigned b){ unsigned c; unsigned m = a; unsigned n = b; if (a < b){ unsigned temp = a; a = b; b = temp; } while (b){ c = a%b; a = b; b = c; } return (m*n) / a; } int main(){ unsigned n, res, temp; while (cin >> n){ if (n > 0){ cin >> temp; res = temp; n--; } while (n--){ cin >> temp; res = getcount(res, temp); } cout << res << endl; } return 0; }
