Summary
The video explains the concepts of HCF (Highest Common Factor) and LCM (Least
Common Multiple) and their relationship using examples. It emphasizes the property
that the HCF is a factor of both numbers, and both numbers are factors of the LCM.
It also demonstrates how to solve problems involving the HCF and LCM.

[00:02](https://www.youtube.com/watch?v=0FpnJAidV1M&t=2) The video explains
the concept of HCF (Highest Common Factor) and LCM (Least Common Multiple) and how
they are related.- HCF is calculated by taking common factors when prime
factorizing the given numbers.
- LCM is calculated by taking the remaining numbers after taking the HCF and
multiplying them.
- The product of the HCF and LCM is equal to the product of the given numbers.
[01:34](https://www.youtube.com/watch?v=0FpnJAidV1M&t=94) When determining if a
number can be the LCM, it is important to consider an additional property related
to HCF and LCM.- Multiplying 75 by a fraction does not give a natural number, so it
cannot be the LCM.
- Multiplying 50 by a natural number gives a natural number, so it can be the LCM.
- However, there is an additional property to consider when determining the LCM and
HCF.
[03:11](https://www.youtube.com/watch?v=0FpnJAidV1M&t=191) HCF is a factor of both
a and b, and a and b are factors of L, which means HCF must be a factor of L.- HCF
is a factor of both a and b.
- A and b are factors of L.
- HCF must be a factor of L.
- It is not possible to have two numbers with HCF as 4 and LCM as 50.
