🔢 Chapter 2: Factors and Multiple

---

📝 Worksheet 4 Overview:

This worksheet focuses on testing and strengthening the understanding of prime numbers, composite numbers, co-prime numbers, twin primes, and prime factorization. It helps students learn the properties of numbers, how they relate to each other, and how to break them down using factors and multiples.


---

🔍 Key Concepts Covered:

1. Prime Numbers:
Numbers that have only two factors – 1 and the number itself.
(Example: 2, 3, 5, 7, 11...)


2. Composite Numbers:
Numbers that have more than two factors.
(Example: 4, 6, 8, 9, 10...)


3. Co-prime Numbers:
Two numbers having no common factor other than 1.
(Example: 4 and 9, 5 and 8)


4. Twin Prime Numbers:
Pairs of prime numbers that have a difference of 2.
(Example: (3, 5), (5, 7), (11, 13))


5. Prime Factorization:
Expressing a number as a product of its prime factors.
(Example: 36 = 2 × 2 × 3 × 3 or 2² × 3²)


6. Common Factors & Multiples:

Finding HCF (Highest Common Factor)

Finding LCM (Lowest Common Multiple)




---

🎯 Learning Objectives:

Identify and differentiate between prime, composite, co-prime, and twin prime numbers.

Use divisibility rules to check for factors.

Perform prime factorization using factor trees or division methods.

Find HCF and LCM of given numbers through the factor method.



---

✅ Worksheet 4 Task Types:

Fill in the blanks using correct terms.

Identify types of numbers from a given list.

Match columns (e.g., match numbers with their properties).

Solve word problems involving HCF and LCM.

Prime factorization problems using factor trees.



---

📌 Tip for Students:

Revise divisibility rules from earlier worksheets.

Memorize prime numbers up to 100.

Practice drawing factor trees to break numbers into prime factors.
