The video tutorial explores the concepts of prime and composite numbers, emphasizing the importance of prime factorization. It introduces the fundamental theorem of arithmetic, which states that every composite number can be uniquely expressed as a product of prime numbers. The tutorial also demonstrates how to calculate the highest common factor (HCF) and least common multiple (LCM) using prime factorization. Additionally, it discusses interesting facts and exceptions related to the theorem, such as its inapplicability to the number one.
