Prime Factorization for GCF and LCM (A) WORKSHEET
Prime Factorization for GCF and LCM (A) WORKSHEET DESCRIPTION
Practice using the prime factorization of pairs of numbers to find the GCF and LCM with venn diagrams in this worksheet. In section A, learners will match numbers to given products of prime factors.
Next, in section B, students use their previous answers and enter the information into pre-drawn venn diagrams in order to find the GCF and LCM of pairs of numbers.
Section C consists of six more questions on either finding the GCF or LCM of pairs of numbers. This time, students are required to find the prime factorization of these numbers themselves, before drawing up their own venn diagrams to answer the questions.
All worksheets are created by the team of experienced teachers at Cazoom Math.
