Strip Diagrams for Common Factors and Multiples

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