Question : What is the least value that should be added to 1812 to make it divisible by 7, 11, and 14?
Option 1: 12
Option 2: 36
Option 3: 72
Option 4: 154
Correct Answer: 36
Solution :
Given:
Number = 1812
Divisors are 7, 11 and 14.
LCM of all divisors can also divide the number.
LCM of 7, 11, 14 is 154.
So, 154 can also divide the number.
When we divide 1812 by 154 we will get the remainder 118.
So, we must add (154 – 118) = 36
Hence, the correct answer is 36.
