Prime Factorisation of Numbers
To find the LCM and HCF of 72, 126, and 168, we first need to prime factorise each number.
72 = 2^3 x 3^2
126 = 2 x 3^2 x 7
168 = 2^3 x 3 x 7
Calculating LCM and HCF
LCM: To find the LCM, we take the highest power of each prime factor present in the numbers.
LCM = 2^3 x 3^2 x 7 = 504
HCF: To find the HCF, we take the lowest power of each prime factor present in the numbers.
HCF = 2 x 3 = 6
Verification of Relationship
To verify that HCF x LCM is not equal to the product of the three numbers, we calculate the product of the numbers:
72 x 126 x 168 = 1612432
HCF x LCM = 6 x 504 = 3024
As we can see, the product of the three numbers (1612432) is not equal to the product of HCF and LCM (3024), which confirms the relationship HCF x LCM ≠ Product of Numbers.
