please tell the reason of prime factorization why do we just take prime factors for lcm

Because that is the easiest way to calculate the LCM for 2 "random" numbers. Assuming you know the prime factorization of each term (which could be hard)

ok you are saying that its easiest way so what about 4 we can also use this in factorization i know its not a prime number but y cant we use this i didnt got the answer of my question yet

The "HCF" is the "Highest Common Factor" of a given list of integers. The highest common factor is the integer which can divide each and every integer in the given list.

The "LCM" is the "Lowest Common Multiple" of a given list of integers. The lowest common multiple is the smallest integer which is divisible by each and every integer in the given list.
