What you need to know

The concepts examiners test on factors, multiples & primes, and what each one is really asking.

Find all factors of a number
List multiples of a number
Identify prime numbers
Understand the difference between factors and multiples

Where marks get lost

The exam technique that separates a correct method from a correct answer.

  • Thinking 1 is a prime number (it is not)
  • Missing factor pairs (always work systematically)
  • Confusing factors and multiples
  • Forgetting that 2 is prime

Thinking 1 is a prime number (it is not).

Which exam boards cover Factors, Multiples & Primes?

All four we support — AQA, Edexcel, OCR and Eduqas. GCSE Maths subject content is set by the DfE, so the topic is common to every board; what changes is the paper structure and the grade boundaries.
