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 g(a, b):
    while b:
        a, b = b, a%b
    return a
n = int(input())
a = list(map(int, input().split()))
ans = a[0]*a[1]/g(a[0],a[1])
for i in a[2:]:
    ans = ans*i/g(ans,i)
print(int(ans))
