Common multiples are shared multiples of two numbers.
Example: Multiples of 2 and 3 → Common multiples: 6, 12, 18
Least Common Multiple (LCM)
The smallest common multiple of two numbers.
Example: LCM of 4 and 6 = 12
What are Factors?
Factors are numbers that divide another number exactly.
Example: Factors of 12 → 1, 2, 3, 4, 6, 12
Common Factors
Factors shared by two numbers.
Example: Factors of 12 and 18 → Common factors: 1, 2, 3, 6
Highest Common Factor (HCF)
