Unit Review: Prime Numbers, HCF, and LCM
Unit Summary: This unit has focused on understanding prime numbers, learning to find
the Highest Common Factor (HCF), and calculating the Lowest Common Multiple (LCM).
Prime numbers are the foundation of number theory, while HCF and LCM play essential
roles in problem-solving and real-life scenarios.
I CAN statement
1. Define and identify prime numbers.
2.
3.
4.
5.

Calculate the HCF of two or more numbers.
Determine the LCM of two or more numbers.
Apply these concepts to real-world problems.
Conceptual Framework:


Prime numbers are the building blocks of other numbers.
HCF and LCM are fundamental for solving problems involving multiple quantities.
Problem-Solving Techniques:
1. Finding Prime Factors
2. Calculating HCF using Prime Factors
3. Calculating LCM using Prime Factors
Memory Prompts:


"Prime numbers have exactly two friends: 1 and themselves."
"HCF is the biggest buddy; LCM is the smallest multiple."
Real-Life Examples:


Scheduling and time management (LCM).
Distributing resources among friends (HCF).
