The Highest Common Factor (HCF) of two or more numbers is the largest number that divides evenly into all of them. The Lowest Common Multiple (LCM) of two or more numbers is the smallest number, a multiple of all of them.
HCF is the largest factor that divides two or more numbers exactly without leaving a remainder, while LCM is the smallest multiple common to two or more numbers. These concepts are related, and the HCF can be used to find the LCM of two or more numbers.
