This is a carefully selected compilation of HCF and LCM questions (highest common factor and lowest common multiple).

HCF and LCM questions

The full range of skills expected at GCSE are covered in these HCF and LCM questions, including finding the HCF and LCM of numbers presented as product of primes.

There are detailed fully-annotated solutions which can be made available to students to go through at home. This can free up considerable time in class.

You can print these questions as an A5 booklet and issue them in class or give them out as a homework. You might also want to make them available for students who want to do some independent study.
