This lesson consists of giving you the necessary "preliminaries" to do fractions. I explain what are factors, divisors, prime and composite numbers, how to do prime factorization, GCFs, LCMs, multiples, and the rules of divisibility. I also explain how to use your graphing calculator to help you find the GCF, LCM and multiples.
