Ex 1.1, 2 Find the LCM and HCF of the following pairs of integers and verify that LCM × HCF = product of the two numbers. (iii) 336 and 54 Finding HCF ∴ H.C.F = 2 × 3 = 6 Finding L.C.M L.C.M = 2 × 2 × 2 × 2 × 3 × 3 × 3 × 7 = 3024 Now, we have to verify that H.C.F × L.C.M = Product of 2 numbers H.C.F × L.C.M = 6 × 3024 = 18116 Product of two numbers = 336 × 54 = 18116 Since L.H.S = R.H.S Hence verified
