Instructions
- 🧲 The Venn Machine: Given two numbers, identify their common factors and build an animated Venn diagram. Discover the HCF (Highest Common Factor) glowing at the heart of the overlap!
- 🚂 Multiple Express: Two trains race along parallel tracks — their stops are multiples. Find where both trains stop at the same station! The first shared stop is the LCM (Lowest Common Multiple).
- 🏆 HCF-LCM Championship: Rapid-fire questions mixing HCF, LCM, co-primes, and the golden rule HCF × LCM = product. Beat the clock and earn streak bonuses!
