Prime Factorization

The video tutorial explains the concept of prime numbers and prime factorization. It defines a prime number as having only two factors: 1 and itself. The tutorial then introduces prime factorization, which involves breaking down a number into its prime factors. Using examples of the numbers 12 and 60, the video demonstrates how to create a factor tree to find the prime factors. The process involves identifying factors, determining if they are prime, and continuing to factorize until all numbers are prime. The video concludes by summarizing the prime factors of the given examples.
