Question 3 - Page 60 In which of these cases is the HCF the same as the common multiplier, like problem (b) where the HCF is 10? Explore a few more examples of this type to understand when this happens.This happens in cases (b) and (c). This is because the other parts of the numbers (like 38 & 21, or 13 & 20) are co-prime (they don't share any factors). Since they don't add any new common factors, the HCF stays just the multiplier.
