Question 1 The ratio of LCM and HCF of the least composite and the least prime numbers is (a) 1 : 2 (b) 2 : 1 (c) 1 : 1 (d) 1 : 3 Now, Least composite number = 4 Least prime number = 2 LCM of 4 and 2 = 4 HCF of 4 and 2 = 2 Thus, Ratio of LCM and HCF = (𝐿𝐶𝑀 )/𝐻𝐶𝐹 = 4/2 = 2/1 Thus, required Ratio is 2 : 1 So, the correct answer is (b)
