More with the GCF
Your Task: Consider the following statements:
Example: GCF (2, 8) = 2 because 2 = 2∙1 and 8 =
2∙4. There is no greater number that
satisfies that condition.
1. Find GCF (3, 12) using your own method . Explain your
reasoning and how you
arrived at your answer. Please do not refer to your textbook at this time. If you are
stuck, I will help you!
2. Fill in the following table. Look for shortcuts!
|a||b||a - b||GCF (a, b)||GCF (a – b, b)|
3. Make a conjecture based on the patterns present in this
table . Are there any
restrictions on your conjecture?
4. Do you think your conjecture is true in all cases? If so, why? If not, why not?
