Multiples and FactorsWorksheet
Practice questions in the order the notes teach them.
A complete 18-page IGCSE guide to multiples and factors. It covers finding factors and multiples, prime and composite numbers, testing whether a number is prime, and writing numbers as a product of prime factors using factor trees and division. It then teaches HCF and LCM by both listing and prime factorisation, and the link HCF × LCM = a × b. The final section applies these to real-world sharing, timing and tiling problems. Every method comes with fully worked examples and common mistakes to avoid. It ends with a summary, a keyword guide for choosing HCF or LCM, and exam tips.
