This video describes different procedures for finding the LCM and GCD of natural numbers. It also illustrates how to use the unit's digit of a number to factorize the number. This is far faster than the traditional methods taught in schools and most of the classes.
The pros and cons of different methods of finding GCD and LCM are outlined in clear terms. This video will be helpful to teachers, parents and students. It particularly useful for the students preparing for CAT type examinations as it gives an insight that is not easily available.
Underrstanding the content of this video will give students an edge in computing LCM and GCD of natural numbers. In a later video we will explain how to compute LCM and GCD of fractions and other numbers.
