Answer 2

Answer:

Mate your question is too long.. so I would do some for an example.. the rest try yourself..

Step-by-step explanation:

32 = 2 x 2 x 2 x 3x 3

37 = 1 x 37

hcf = 1

lcm = 2 x2 x 2x 3 x 3x 37 = 1184

18 = 2x 3 x 3

63 = 7 x 3 x 3

hcf = 3 x3 =9

lcm = 3 x3 x2 x7= 126.

HOPE IT HELPS..
