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 Python3 (judge verdict: Accepted)

def lcm_base(x, y):
    return (x*y) // math.gcd(x, y)


def lcm_list(numbers):
    return reduce(lcm_base, numbers, 1)


import math
from functools import reduce

n = int(input())
alist = list(map(int, input().split()))

print(lcm_list(alist))
