Answer 2

Answer:

HCF of 135 and 75 by prime factorization :

135  =  5 × 3 × 3 × 3

75   =  5 × 5 × 3

Common factors = 5 × 3

HCF = 15

LCM of 135 and 75 :

prime factors of 135 and 75 =  3 × 3 × 3 × 5 × 5

LCM = 675

Now HCF of 135, 75 and 20 by prime factorization :

135  =  5 × 3 × 3 × 3

75   =  5 × 5 × 3

20 =   2 × 2 × 5

Common factor = 5

HCF = 5

LCM of 135, 75 and 20

LCM = 2 × 2 × 3 × 3 × 3 × 5 × 5

LCM  = 2700

HCF of 135 and 75 is 15 and LCM is 675

HCF of 135, 75 and 20 is 5 and LCM is 2700
