I am trying to store the (non-repetitive) numbers in B = [3,5] after factorizing 225 = 3 x 3 x 5 x 5, but executing the code it stores only one, i.e. B = [3].

% 
A = factor(225);
B(1) = A(1);
flag = 0;
for i = 1:length(A)-1;
  for j = i + 1;
      if A(i) == A(j)
          flag = flag + 1;
          break
      end
  end
if flag == 0;
  B(count) = A(i);
  count = count + 1;
end
end
