if m is a positive integer and m ^ 2 is divisible by 39 , then the largest positive integer that must divide m is ?
"m ^ 2 is divisible by 48 so m ^ 2 must be multiple of 48 . if the value of m is multiples of 13 then it will satisfy the condition . if we if m is 12 or 24 or 36 then it ans is e but if m = 39 then answer should be 16 . is the question right ? or am i missing some thing ? e"
multiply(const_3, divide(divide(39, const_3), const_3))
