I like this method of finding GCF and LCM. However, I don't see the need of using the divisor of 1. My students are not allowed to use 1 in the prime factorization of a number because it is not prime. Also dividing by 1 is not going to change the answer so why do it? Another memory technique I see with this method is this: When multiplying the factors down then across the bottom you are forming the letter "L". Therefore that is the Least Common Multiple.
