`What is the least number that when doubled will be exactly divisible by 12, 14, 18, and 22?`

A. 1216

B. 1436

C. 1286

D. 1386

**Answer: D. 1386**

**Solution:**

LCM of 12, 14, 18 and 22 = 2772

Hence the least number which will be exactly divisible by 12, 14, 18 and 22 = 2772

2772 ÷ 2 = 1386

1386 is the number which when doubled, we get 2772.

**Hence, 1386 is the least number which when doubled will be exactly divisible by 12, 14, 18 and 22.**
