To buy an equal number of chocolates of three brands In the least number of boxes of each kind,then we have to find LCM of 30,24 and 15.Finding LCM will help to find the answer of this question.
So the LCM of 30,24 and 15 is 120.
So total number of chocolates needed for each brand =120
So 1st brand= 120÷30=4 boxes
2nd brand= 120÷24=5 boxes
3rd brand= 120÷15=8 boxes.
