Composite and Prime Numbers Concepts

This video tutorial covers the concepts of prime and composite numbers, explaining how to identify them using factor pairs and divisibility rules. The lesson includes examples of numbers like 32, 13, 45, and 54, demonstrating how to determine if they are prime or composite. The tutorial emphasizes the importance of understanding divisibility rules and provides a clear distinction between prime numbers, which have only two factors, and composite numbers, which have more than two. The video concludes with a summary of key concepts and a reminder of the rules for identifying prime and composite numbers.
