Question
Using prime factorization, find the HCF and LCM of 1152, 1664 In case verify that HCF × LCM = product of given numbers.
Solution
Prime factorization:
1152 = 27 × 32
1664 = 27 × 13
HCF = product of smallest power of each common prime factor in the numbers
= 27 = 128
LCM = product of greatest power of each prime factor involved in the numbers
= 27× 32 × 13 = 14976
