Problem:
Least Common Multiple

Find the least common multiple (LCM) of given n integers.

Input

n
a1 a2 ... an

n is given in the first line. Then, n integers are given in the second line.

Output

Solution in C (judge verdict: Accepted)

#include<stdio.h>
int main(void)
{
	int n,a[10],max=0,c=0,i;
	scanf("%d", &n);
	for(i=0; i<n; i++)
	{
		scanf("%d", &a[i]);
		if(max<a[i])
		max=a[i];
	}
	int k=max;
	while(1)
	{
		for(i=0; i<n; i++)
		{
			if(k%a[i]!=0)
			break;
			if(i==n-1)
			c=1;
		}
		if(c>0)
		{
			printf("%d\n", k);
			break;
		}
		k+=max;
	}
	
	return 0;
