Rohnda is in charge of buying food for the school picnic, she found that hot dogs are in packages of 24, buns in packages of 18, ketchup in boxes of 12, and mustard in boxes of 15. what is the least number of students that can be feed if each student receives 1 of each item and there are none left over?

This is just like finding the LCM of

24, 18 ,12, and 15

24 = 2x2x2x3

18 =2x3x3

12 = 2x2x3

15 = 3x5

The LCM = 2x2x2x3x5 = 120
