This 16 page resource begins with the definitions for the words factor, greatest common factor and least common multiple. It continues by explaining and illustrating what a factor tree is and how to construct and use a Venn Diagram as a graphic organizer.
After finding the GCF, how to find the least common multiple is explained by using the same Venn Diagram. Two pages of step-by-step examples are given, followed by three student practice pages. One of the practice pages is entitled “What’s Missing” and requires the student to read a Venn Diagram to find the two missing numbers, their factors, the LCM and the GCF.
This resource is an effective tool when teaching fractions. It is also applicable and helpful in algebra when students are asked to find the LCM or GCF of a set of algebraic terms such as: 25xy, 40xyz. (LCM = 200xyz; GCF = 5xy.) A page of 12 blank Venn Diagrams and an answer key are included.
