15.1.1 Part 1 find the H.C.F and L.C.M of algebraic expressions using factorisation.

X AKU find the highest common factor (H.C.F.) and the least common multiple (L.C.M.) of algebraic expressions using factorisation. This Video gives a very simple method to calculate LCM and HCF of Algebraic Polynomials and Quadratic Expressions and their properties. Useful for 7th, 8th, 9th and 10th entrance exams
