Greatest Common Factor (GCF) is the biggest number which can divide two or more numbers. We can find the GCF by applying prime factorization to the numbers in questions. Another very similar concept that also requires prime factorization is called the least common multiple (LCM). In this lesson, we are going to use the "cake method" to solve the questions.
