Factors, Multiples and Primes

Identify factors, multiples, prime numbers, prime factors, square and cube numbers. This sits within the Number strand of the UK National Curriculum for Key Stage 2 (KS2) maths, and every question is written to match what a Year 6 pupil is expected to know by the end of the school year — not simplified or extended beyond the actual curriculum content for this topic.

This topic has its own question bank mixing easy, medium and hard questions, and you can choose a specific difficulty (or Mixed, for a bit of everything) before starting. Each attempt pulls a fresh, randomised set rather than repeating the exact same questions in the same order, so your child can practise Factors, Multiples and Primes as many times as they need without the answers becoming memorised rather than understood.

Yes — the KS2 maths SATs, taken at the end of Year 6, assess the full National Curriculum for that year, which includes factors, multiples and primes alongside every other topic listed on the Year 6 Maths Challenge page. This practice page isn't formatted as a SATs-style exam paper, but reinforcing the underlying method here — with an explanation every time, right or wrong — builds the same skill a SATs question on this topic would test.
