LCM and HCF of two numbers are 54 and 9 respectively. If one of the numbers is 18, then find the other number.

Correct option is C

Given:

LCM of two numbers = 54

HCF of two numbers = 9

One number = 18

Formula Used:

Number1 × Number2 = LCM × HCF

Solution:

18 × Other number = 54 × 9

Other number =$$\frac{486}{18}$$​ = 27
