Displaying Perfect Numbers and Factors in JTextArea box

Question

I had to write a program that displays the perfect numbers along with their factors in a scrollable JTextArea Box. I have my program written but when it displays the output all that appears is
Number Factors
in my box with no numbers of factors listed. If anyone can help me with this problem please respond...here is my program so far
public class Perfection
     public static void main (String args [])
          String output, factor;
          long min, max, factors, sum, lowerBound;
          JTextArea text = new JTextArea (30,50);
          JScrollPane scroll = new JScrollPane (text);
          sum = 0;
          output = " ";
          factor = " ";
          output += "Numbers\t" + "Factors";
          min = Long.parseLong (JOptionPane.showInputDialog ("Enter the lower bound of your range"));
          max = Long.parseLong (JOptionPane.showInputDialog ("Enter the upper bound of your range"));
          while (min > 0 && max > min)
               for (lowerBound = min; lowerBound <= max; lowerBound++)
                    for (factors = 1; factors < lowerBound; factors ++)
                         if (lowerBound % factors == 0)
                              factor += factors + ", ";
                              sum += factors;
                    if (lowerBound == sum)
                         output += "\n";
                         output += lowerBound + "\t" + factor;
               text.setText (output);
               JOptionPane.showMessageDialog (null, scroll, "Range of " + min + " to " + max, JOptionPane.PLAIN_MESSAGE);
          JOptionPane.showMessageDialog (null, "Restart program and enter a range in which the lower bound is positive and the upper bound is greater than the lower bound",
                                                                           "Range of " + min + " to " + max, JOptionPane.WARNING_MESSAGE);
          System.exit (0);
}
