Using prime factors and Venn Diagrams students are able to calculate the highest common factor and lowest common multiple of two or more numbers.  As learning progresses they apply their learning to solve real life problems.

Differentiated Learning Objectives

• All students should be able to calculate the LCM and HCF of a pair of integers using Prime Factors
• Most students should be able to calculate the LCM and HCF of any number of integers using Prime Factors
• Some students should be able to solve real life problems through the use of calculating the HCF or LCM.
