题目大意:求最小公倍数,用辗转相除法。

 1 #include <stdio.h> 2 int main () 3 { 4     int gcd(int a,int b); 5     int a,b,n,i,c; 6     while (scanf("%d",&n)!=EOF) 7     { 8         scanf ("%d",&a); 9         for (i=1; i<=n-1; i++)10         {11             scanf ("%d",&b);12             c=gcd(a,b);13             a=a/c*b;14         }15         printf ("%d\n",a);16     }17     return 0;18 }19 int gcd(int a,int b)20 {21     if (b==0)22         return a;23     return gcd(b,a%b);24 }
