Chapter 2 : HCF and LCM

Factors of algebraic expression is obtained and then common factor of the expression is collected. This common factors is the H.C.F.

To find the L.C.M. we find the common factors and then we multiply then by the left out factors.

Example 1. If P(x) = (x3 + 1) (x - 1) and Q(x) = (x2 - x + 1) (x2 - 3x + 2), find the GCD and LCM of P(x) and Q(x).

Solution:

GCD

LCM
