More about these tests
Grade 7 writes numbers as a product of prime factors and uses it to find the HCF and LCM.
Every answer is marked as you go, with the working shown, so a wrong answer teaches something instead of only costing a mark. The most common mistakes: Using a factor that is not prime (like 4 or 6), and swapping the HCF and LCM.
