Study Notes

Mathematics: Algebra & Number Systems

Key Concept: The Fundamental Theorem of Arithmetic
Every composite number can be expressed (factorised) as a product of primes, and this factorization is unique, apart from the order in which the prime factors occur. You use this for finding HCF and LCM.
* HCF (Highest Common Factor): The largest number that divides two or more numbers exactly. Found by taking the smallest power of each common prime factor.
* LCM (Lowest Common Multiple): The smallest number that is a multiple of two or more numbers. Found by taking the highest power of all prime factors involved.
* Relationship: For any two positive integers a and b, HCF(a, b) $\times$ LCM(a, b) = a $\times$ b.
