Mastering LCM: Unveiling the Magic of Factor Trees and Prime Factorization

The video tutorial demonstrates how to find the least common multiple (LCM) using factor trees. It begins with an introduction to the concept of LCM and the method of prime factorization. The instructor explains the inefficiency of this method compared to the latter method. The video then details the factorization of given values, aligning their prime factors vertically to find the LCM. Finally, the LCM is calculated by multiplying the shared prime factors.

Describe how to align the prime factors vertically when finding the LCM.

What is the final result of multiplying the shared factors to find the LCM?
