Find the LCM and HCF of two numbers | Product of LCM and HCF is equal to Product of two numbers
03:10 Q2. Find the LCM and HCF of the following pairs of integers and verify that LCM × HCF =
product of the two numbers.
03:25 (i) Find the LCM and HCF of 26 and 91 (ii) Find the LCM and HCF of 510 and 92 (iii) Find the LCM and HCF of 336 and 54
03:34 Product of prime factors using factor tree.
04:05 Obtain HCF
04:40 Take LCM
05:46 Verification:HCF (a , b ) × LCM ( a , b ) = a × b
06:44 (ii) Find the LCM and HCF of 510 and 92
10:15 (iii) Find the LCM and HCF of 336 and 54
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.
