This sheet covers prime factorisation and finding the HCF and LCM of two (or three) numbers, with exam-type questions that gradually increase in difficulty.
Note that these questions cover the full range of skills tested in GCSE and IGCSE for this topic and there are some problem-solving questions at the end.
Detailed solutions are included, as is a new style of PowerPoint, which allows the questions and their solutions to be easily selected for enlarged display onto a screen, one at a time – this makes it easier (and quicker) to go through the solutions in class.
