Solving LCM Word Problems

The video tutorial covers solving word problems involving the least common multiple (LCM). It starts with a problem about matching the number of hot dogs and buns, explaining how to find the LCM of 8 and 12. The tutorial then calculates the number of packages needed for both items. Another example is provided with a swimming and diving practice schedule, finding the LCM of 2 and 3 to determine when both activities coincide.

What is the main problem discussed in the video?

• Finding the least number of hot dogs and buns needed.

• Determining the nutritional value of hot dogs.

• Finding the best brand of buns.

• Calculating the price of hot dogs.
