In bold and underlined text I have mentioned the common factors.

144 = 2*2*2*2*3*3

180 = 2*2*3*3*5

so,

HCF = 2*2*3*3

= 36

216 = 2*2*2*3*3*3

108 = 2*2*3*3*3

36 = 2*2*3*3

We will list all the common factors and count them once

LCM = 2*2*3*3*2*3

= 216

(one 3 is common in two numbers so we will count it once)

FOR PRIME FACTORISATION REFER TO ATTACHMENT...
