For a given n, write the function lcmSum(n), defined as follows:
                    
For example for :
  >> lcmSum = @(n) sum(lcm(n,1:n));
  >> lcmSum(20)
  ans =
        2320
Since the sum grows very fast, please present your answer as a character string array and please limit the cody program size of the function to 150.
