What must be the least number of the students in a group such that they can be arranged
in lines of 10, 15 and 25 independently and can also be arranged in a square as a group?

• 900
  
  LCM of 10, 15, 25 = 150
  With given condition that stuidents can also be arranged in a square as a group, so finding least multiple of 150 which is also a square term, we have 150x6=900=30²
