Which of the following numbers is NOT divisible by 16?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 16826.
The divisibility rule of 16: Any number that has 4 or greater than 4 digits is divisible by 16 if and only if the last 4 digits of the number are divisible by 16.
Option 1 = 16826
Last 4 digits = 826/4 = 206.5
Option 2 = 17776
Last 4 digits = 776/4 = 194
Option 3 = 5168
Last 4 digits = 168/4 = 42
Option 4 = 18016
Last 4 digits = 8016/4 = 2004
Hence, only 16826 is not divisible by 16
