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

Print the least common multiple of the given integers in a line.

Constraints

2 ≤ n ≤ 10

1 ≤ ai ≤ 1000

Product of given integers ai(i = 1, 2, ... n) does not exceed 231-1

Sample Input 1

Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

class C
{
	static void Main()
	{
		Console.ReadLine();
		var a = Console.ReadLine().Split().Select(int.Parse).ToArray();
		Console.WriteLine(a.Aggregate(Lcm));
	}

	static int Gcd(int a, int b) { for (int r; (r = a % b) > 0; a = b, b = r) ; return b; }
	static int Lcm(int a, int b) => a / Gcd(a, b) * b;
}
