If HCF and LCM of two numbers are respectively (n – 1) and (n² – 1)(n² – 4), then the product of the two numbers will be:
(3)
We have, HCF = (n – 1) and LCM = (n² – 1)(n² – 4)We know that product of two numbers = LCM × HCFSo product of two numbers = (n – 1)(n² – 1)(n² – 4)= (n – 1)(n – 1)(n + 1)(n² – 4)= (n + 1)(n – 1)²(n² – 4)
