These 2 clips summarises how we can find HCF and LCM of 2 or more numbers
Clip 1: Observe what are the factors 'circled' in each case
When we look for Highest common factor, technically, we are looking for the 'lowest' power.
For the Lowest common multiple, technically, we multiply the prime factors with the highest power.
Clip 2: Some of us learnt to find the HCF and LCM using the division method.
The clip attempts to show how these 2 methods (i.e. Long Division method and Index Notation Method) are related to each other - the same thinking behind, though the representation looks different.
