The correct formulation is THIS: 

    List three-digit smallest and largest numbers what are divisible by 8, 12 and 16 respectively.


Solution 

The Least Common Multiple of the numbers 8, 12 an 16 is 48.


Therefore, the integer numbers that are divisible by 8, 12 and 16 are those and only those that are multiple of 48.


The smallest 3-digit integer multiple of 48 is  144.

    How to find it ? - Divide 100 by 48:  100%2F48 = 2.083 (approximately);

    So, consider 48*3 - it is exactly 144.



The largest 3-digit integer multiple of 48 is  960.

    How to find it ? - Divide 999 by 48:  999%2F48 = 20.81 (approximately);

    So, consider 48*20 - it is exactly 960.



Answer.  The largest 3-digit integer divisible by 8, 12 and 16 is 960.

         The smallest 3-digit integer divisible by 8, 12 and 16 is 144.
