Understanding LCM and HCF

LCM: The Least Common Multiple of two or more integers is the smallest positive integer that is divisible by each of the integers without leaving a remainder. For example, the LCM of 4 and 6 is 12.

HCF: The Highest Common Factor of two or more integers is the largest positive integer that divides each of the integers without leaving a remainder. For example, the HCF of 18 and 24 is 6.
