Here is your answer

HCF is 12

LCM is 336

Answer 2

Answer:

HCF of 84 and 48

       1)  84 = 2 × 2 × 3 × 7

       2)  48 = 2 × 2 × 2 × 2 × 3

⇒ here three factor are common b/w them i.e, 2,2 and 3

∴ So the HCF of 84 and 48 is = 2 × 2 × 3

                                                 = 12

LCM of 84 and 48

     1)  84 = 2 × 2 × 3 × 7

    2)  48 = 2 × 2 × 2 × 2 × 3

∴ So the LCM of 84 and 48 is  = 2 × 2 × 2 × 2 × 3 × 7

                                                  = 336
