Using Prime Factorization to find
GCF and LCM
Grade Level:
6
Subject:
Math
Topic:
Using Prime Factorization to find GCF and LCM
Objective:
Students will be able to list the prime factors that make up a given number and write the factors in exponential form where applicable.
Students will be able to compare 2-3 sets of prime factor lists to determine common base numbers in the set and identify the greater value of these common base numbers.
Students will be able to use the prome factorization of 2-3 numbers to find the GCF and LCM of these numbers.
