Dividing Numbers and Prime Factorization

This video tutorial demonstrates how to find the prime factors of a number using the ladder method. The example used is the number 336, which is broken down into its prime factors by dividing it by the smallest possible prime numbers. The process involves checking divisibility, switching to the next smallest prime when necessary, and using exponential notation to simplify the expression of the prime factors. The tutorial emphasizes the importance of understanding prime numbers and the methodical approach to factorization.
