The only even prime number is 2. It is the only number divisible by 1 and itself. All other even numbers are divisible by 2 making them composite numbers. 2 is a unique prime number because it is the only one that is even and has exactly two factors.
In this chapter students explore prime and composite numbers. It covers prime factorization methods and the concept of factors and multiples. The chapter also introduces divisibility rules. Understanding prime factorization helps solve problems related to HCF and LCM. This chapter enhances logical thinking and number analysis skills.
