The need for such concepts arises, among other things, from the manipulation of fractions. The least common multiple is commonly used to find a common denominator for different frations; this is required to compare, add, or subtract two (or more) fractions.

LCM (Least Common Multiple) and HCF (Highest Common Factor), also known as GCD (Greatest Common Divisor), are mathematical concepts that have been used since ancient times in various cultures. They were initially used in solving problems related to fractions and division, and over time, their properties and applications have been further developed in number theory and algebra. Their concepts have evolved and been refined through the works of mathematicians like Euclid, Fermat, and Euler.
