The video tutorial covers the concepts of greatest common factor (GCF) and least common multiple (LCM) through word problems. It includes two examples: arranging plants in a garden using factor pairs and determining when two volunteers will work together using LCM. The tutorial encourages students to practice these concepts and provides a clear explanation of the problems and solutions.
