Factors, Multiples and Primes | Edexcel GCSE Foundation | 40 Worked Examples

A complete, step-by-step worked-solutions pack on Factors, Multiples and Primes for Edexcel GCSE Foundation Maths (1MA1). 40 exam-style questions build from the basics (listing factors and multiples, spotting prime numbers, writing a number as a product of its prime factors in index form) up to full HCF and LCM problems and real-world worded questions (buses, ribbons, packing, alarms).

Every single question has a fully worked solution written for students who need it explained clearly, with no jargon: one small step at a time, a plain-English note on the right of every working line, and the final answer highlighted. Edexcel mark-scheme codes (M1, A1, B1 and the P1 process marks Edexcel uses on worded problems) are annotated exactly where they are earned, so students learn how marks are actually awarded.

Questions are grouped by difficulty (Easy, Standard, Challenging) so the pack works as a gentle warm-up, focused practice, or grade-5 stretch. Ideal for homework, revision, cover lessons or 1-1 tuition. Answers included. Topics covered: factors, multiples, prime numbers, product of prime factors, index form, HCF, LCM, and HCF x LCM = a x b.
