Real Numbers: Finding the LCM

The video tutorial explains the concept of least common multiple (LCM) using examples of bells ringing at different intervals. It introduces the factorization method for finding LCM, especially for larger numbers, and explains the highest common factor (HCF) or greatest common divisor (GCD). The tutorial also covers the relationship between the product of two numbers and their LCM and HCF, using practical examples to reinforce understanding.
