Question : What will be the least number which when doubled will be exactly divisible by 12, 14, 16, and 18?
Option 1: 636
Option 2: 428
Option 3: 504
Option 4: 226
Correct Answer: 504
Solution : Given: The numbers are 12, 14, 16, and 18. LCM of (12, 14, 16, 18) = 16 × 9 × 7 = 1008 The least number which when doubled will be exactly divisible by 12, 14, 16, and 18 = $\frac{1008}{2}$ = 504 Hence, the correct answer is 504.
