Factor trees

A worksheet for KS3 students to practise more advanced prime factorisation using factor trees (they should be able to make short factor trees of 2-3 steps before attempting this sheet). This will help as a buildup to HCF and LCM calculations; and as an aid to indices and powers too. This resource includes a blank copy which can be used for teacher (or peer) directed tasks as well as one example.
