In this video, how to find the prime factors of given numbers using factor tree is explained.LCM and HCF of two numbers is obtained by prime factorization of numbers.Basic Algebra is included.That is Find the LCM and HCF of two numbers by the prime factorisation method.

HCF is the Product of the smallest power of each common prime factor in the numbers.
LCM is the Product of the greatest power of each prime factor, involved in the numbers.

Fundamental Theorem of Arithmetic: Every composite number can be expressed or factorised as a product of primes, and this factorisation is prime factorisation.
The prime factorisation of a natural number is unique, except for the order of its factors.

00:02 Q6. Explain why 7 × 11 × 13 + 13 and 7 × 6 × 5 × 4 × 3 × 2 × 1 + 5 are composite numbers.
00:41 defination of composite number :
composite number has atleast one factor other than 1 and the number itself.
