Understanding Least Common Multiple with Cookies

The video tutorial explains how Mason can buy an equal number of chocolate and lemon cookies by determining the least common multiple (LCM) of the cookies per package. It uses a table to calculate the number of cookies in each package and identifies 120 as the LCM of 24 and 30. Mason needs to buy five packages of chocolate cookies and four packages of lemon cookies to have 120 of each type.

What is the main problem Mason is trying to solve?

• Finding the number of cookies in a single package

• Finding the best cookie recipe

• Finding the least number of each type of cookie to buy equally

• Finding the cost of cookies
