Question

3. Find the HCF and the LCI
= HCF X LCM.
(b) 81, 82​

Answer 1

Answer:

HCF = 1

LCM = 6,642

Product of HCF and LCM = 6,642

Step-by-step explanation:

Finding HCF by listing out all factors

81 = 1,3,9,27,81

82 = 1,2,41,82

HCF = 1

Finding LCM

Since we know 81 and 82 are co-prime numbers, we can simply multiply them.

81 × 82 = 6,642

HCF × LCM = 1 × 6,642

= 6,642
