Question : The least common multiple of 48 and 64 is _____ times the highest common factor of 12 and 18.
Option 1: 28
Option 2: 32
Option 3: 24
Option 4: 16
Correct Answer: 32
Solution : The least common multiple (LCM) of 48 and 64 is 192. The highest common factor (HCF) of 12 and 18 is 6. Therefore, the LCM of 48 and 64 is $\frac{192}{ 6}$ = 32 times the HCF of 12 and 18. Hence, the correct answer is 32.
