解题报告:
先置n个元素最小公倍数为k = 1,然后依次将n个元素与k求最小公倍数,两个两个求。每个将两个元素的最小公倍数与下一个元素继续求最小公倍数。
详细情况见代码。
#include<stdio.h> int func(int m, int n)
{
int i;
if(m > n)
{
int t = m;
m = n;
n = t;
}
for(i = n; ; i++)
{
if(i%m == && i%n==)
break;
}
return i;
}
int main()
{
int n, m;
while(scanf("%d", &n) == )
{
int i, k = ;
for(i = ; i < n; i++)
{
scanf("%d", &m);
k = func(m, k);
}
printf("%d\n", k);
}
return ;
}
