LCM of n numbers

Input  :

First line contains the number of numbers that are input  'n', where n>1

Next line contains 'n' positive integers whose LCM is to be calculated.

Output  :

One line containing the LCM of the 'n' numbers

  while (b!=0){
   g=a%b;
   a=b;
   b=g;}

return a; // a is the gcd
}
