No neither do I.....

I could go for the trival answer and say that Mai bought the greatest number, which is 45,

because 45 is bigger than both 36 and 18.      

Melody....I'm taking a guess here.....but....I believe the rest of the question might be....."What is the greatest number of boxes that come in a pack??"

If so......the answer is 9 boxes.........the greatest common divisor of 18, 36 and 45
