Question

1. If ab=180 and HCF(a, b) =3, then find the LCM(a, b)

Answer 1

Answer:

LCM= 60

Step-by-step explanation:

HCF(a,b) × LCM (a,b) = a×b

3 × LCM (a,b) = 180

LCM (a,b) =180÷3

= 60

Answer 2

Given : ab = 180

HCF = 3

To find : LCM (a, b)

Solution: ab = 180

HCF = 3

LCM × HCF = product of two numbers

LCM × 3 = 180

LCM = 180 ÷ 3

LCM = 60
