Q. 164.4( 14 Votes )

144 cartons of Coke Cans and 90 cartons of Pepsi Cans are to be stacked in a Canteen. If each stack is of the same height and is to contain cartons of the same drink, what would be the greatest number of cartons each stack would have?

Answer :

To find greatest number of cartons each stack would have, we should find HCF of 144 and 90


Prime factors of 144 = 2 × 2 × 2 × 2 × 3 × 3


Prime factors of 90 = 2 × 3 × 3 × 5


Therefore HCF of 144 and 90 is: 2 × 3 × 3 = 18


Therefore the greatest number of cartons each stack would have is: 18
