Did I solve this problem right? Here is the question: Use least common multiple or greatest common factor to solve this problem. Mark has 153 hot dogs and 261 hot dog buns. He wants to put the same number of hot dogs and hot dog buns on each tray. What is the greatest number of trays that Mark can use to accomplish this? My answer is 9 because I used the greatest common factor. Is this correct? Thanks.
