HCF and LCM

HCF(Highest Common Factor) is the highest number that exactly divides all the number whose HCF it is. It is denoted by HCF(a, b), where “a” and “b” are the numbers for which we want to find the highest common factor. For example, if you have numbers like 2, 4, and 6, the smallest number that all of them can divide into is 12.

LCM(Lowest Common Multiple) of two or more numbers is smallest number that is multiple of both the numbers. It is denoted by LCM(a, b), where “a” and “b” are the numbers for which we want to find the least common multiple. For example, if you have numbers like 6 and 30, the largest number they can both be divided by is 6.

Least Common Multiple (LCM) is the smallest number that can be evenly divided by two or more given numbers. Whereas Highest Common Factor (HCF) is the largest number that can evenly divide two or more given numbers.

LCM and HCF can be easily found using two main methods:

• Division Method
• Prime Factorization Method

In this article, we will learn about HCF and LCM Definition, application of HCF and LCM and others in detail.
