find the hcf and lcm of the following integers by expressing them as p – InterviewSolution

1.

find the hcf and lcm of the following integers by expressing them as product of primes 1. 18,81,and 108

Answer»

First find prime factors of 18, 81 and 108

18 = 2*3*381 = 3*3*3*3108 = 2*2*3*3*3

HCF is Highest common factor so HCF for given numbers = 9

LCM Least Common MultipleSo LCM = 2*2*3*3*3*3 = 324
