If the HCF of two numbers is 2 and their LCM is 70, then the numbers are: Choose one:
A) 2, 235  B) 6, 70  C) 4, 70  D) 14, 10  E) 15, 20
Explanation:   HCF of the two numbers is 2   Let us take two numbers are x and y   Their LCM= 70   LCM is the product of two numbers.   LCM/HCF = 70/2 = XY/2   xy=70×2 = 140   xy = 140   x = 14, y = 10 or x = 70, y = 2.   But according to the options, the numbers are x = 14 and y = 10.   Answer: 14, 10
