Answer 1

HCF of 16.5,0.45 and 15 is 1500/100 =15ans.

                              AND

LCM of 0.6,9.6 and 0.36​ is;

0.6 = 2 x 3 x 10^-1

9.6 = 2 x 2 x 2 x 2 x 2 x 3 x 10^-1

=> 2^5 x 3 x 10^-1

0.36 = 2 x 2 x 3 x 3 x 10^-2

=> 2^2 x 3^2 x 10^-2

LCM:

2^5 x 3^2 x 10^-1

=> 2 x 2 x 2 x 2 x 2 x 3 x 3 / 10

=> 288 / 10 = 28.8

hope it helps..
