The process of identifying the Least Common Denominator (LCD) within a group of expressions revolves around pinpointing the smallest value that can be evenly divided by each denominator in that group. This typically necessitates the discovery of the least common multiple among the denominators, which could require the utilization of various multiplication methods such as factoring or prime factorization.
