MATHEMATICS HCF and LCM § Square and square root § Percentage and its application (profit and loss, simple and compound interest) § Ratio and Proportion § Algebraic simple equation and its solution § Set- its elements, operations on set § Geometry of Triangles, quadrilaterals and circles § Basic Geometrical Concept HCF and LCM Highest Common Factor and Lowest Common Multiple I've identified six methods for finding the HCF and LCM of two numbers. I'll explain each method here and identify any pros and cons. 1. Listing Source: mathx.net There's no harm in the listing method. It's brilliant in terms of underlying conceptual understanding - students can see exactly what they're trying to achieve here. List all the factors of the two numbers and find the biggest number that's in both lists - that's your HCF. List all the multiples of two numbers and find the smallest number that's in both list
