GCF and LCM Word Problem Challenge

The video tutorial covers two mathematical problems: finding when Ronald and Tim will do laundry on the same day using the least common multiple (LCM), and organizing basketball teams with equal players using the greatest common factor (GCF). The tutorial explains how to calculate multiples and use prime factorization to solve these problems.

What mathematical concept is used to determine when Ronald and Tim will both do laundry on the same day?

• Least Common Multiple

• Addition

• Prime Factorization

• Greatest Common Factor

If Ronald does laundry every 6 days and Tim every 9 days, what is the first day they will both do laundry together?

• 18th day

• 21st day

• 15th day

• 12th day
