How to Use Prime Factor Trees to find Prime Factors #5

The video tutorial explains prime factors and how to find them using factor trees. It begins with a basic introduction to prime factors, using the number 12 as an example. The tutorial then demonstrates the use of factor trees to find prime factors of more complex numbers, such as 220 and 112. The process of prime factorization is explained, emphasizing that the order of factorization does not affect the final set of prime factors.
