Q. The HCF of two numbers is 23 and the other two factors of their LCM are 13 and 14. The larger of the two numbers is :
Answer: 322
Notes: Let the numbers be 23x and 23y where x and y are co-prime to each other. ∴ LCM = 23xy As given, 23xy = 23 $latex \times$ 13 $latex \times$ 14 ∴ x = 13, y = 14 ∴ The larger number = 23y = 23 $latex \times$ 14 = 322 Hence option [C] is correct answer.
