This worksheet extensively covers finding the highest common factor and lowest common multiple of pairs of numbers. We aim to equip learners with solid methods they can replicate.

Section A consists of six Venn diagrams into which students will enter factors of pairs of numbers before identifying the HCF of each pair.

In section B, learners will list the first 10 multiples of numbers, identify common multiples and choose the LCM of five pairs of numbers.

Lastly, section C comprises 15 mixed HCF and LCM questions to provide good practice for your students.
