Question

Find HCF and LCM of following pairs of integers
by prime factorisation method and verify that LCM
* HCF = Product of the two numbers:
77,979​

Answer 1

Step-by-step explanation:

prime factorization of 77 = 7×11

prime factorization of 979= 11×89

HCF= 11

LCM= 11×7×89

for verification:

LHS=LCM×HCF =11×7×89×11

RHS=PRODUCT OF NUMBERS = 77×979

THEREFORE,LHS = RHS
