If m is a positive integer and m^2 is divisible by 54, then the largest positive integer that must divide m is?	Choose the most appropriate option:
A) 3  B) 6  C) 18  D) 12  E) 16
M^2 is divisible by 48 so M^2 must be multiple of 48.   If the value of M is Multiples of 18 then it will satisfy the condition. If we If M is 12 or 24 or 36 then it ans is C but if M = 54 then answer should be 16.   Is the question right? Or am i missing some thing?   18
