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 Ruby (judge verdict: Accepted)

def aux(l)
  l.inject(1){|s,x| s.lcm(x)}
end

def main
  dat=[]
  fh=STDIN
  #fh=File.new("x.txt", "r")
  n = fh.gets.chomp.to_i
  l=fh.gets.chomp.split.map(&:to_i)
  puts aux(l)
end

if $0 == __FILE__ then
  main
end
