Using GCF's & LCM's Open Response

The video tutorial explains how to solve a math problem involving greatest common factors (GCF) and least common multiples (LCM) using a real-world scenario. At a store's grand opening, every 10th customer receives a free sticker, and every 25th customer receives a free T-shirt. The tutorial is divided into three parts: Part A calculates the number of customers receiving free stickers, Part B calculates those receiving free T-shirts, and Part C identifies customers receiving both items. The tutorial uses organized lists to solve each part, demonstrating the application of GCF and LCM in practical situations.
