Strip Diagrams for Common Factors and Multiples

Sample questions
  1. Starting with numbers 16 and 40, use the applet to find and explain their greatest common factor .
  2. Using the picture for your explanation from #1, to explain what must be the greatest common factor of 16 and 40 - 16 = 24.
  3. Use your arguments above to justify the Euclidean Algorithm for finding GCF of two numbers.
