Question
HCF of two numbers 60 and 100 can be expressed in the
form of (20m β 120) whereas LCM of these two numbers can be expressed in the form of (40n β 20). Find the ratio of (n Γ m).Solution
HCF of 60 and 100 = 20 LCM of 60 and 100 = 300 According to the question, => 20m β 120 = 20 => m = 7 And, 40n β 20 = 300 => n = 8 Required answer = n x m = 56
