Three drums contain 36 litres, 45 litres and 72 litres of oil. What bigg
measure all the different quantities exactly?​

Answer 1

Answer:

To measure all the different quantities exactly = HCF of 36, 45 and 72.

Prime factor of 36 = 2x 2x 3x 3

Prime factor of 45 = 3x 3x 5

Prime factor of 72 = 2x 2x 2x 3x 3

so HCF of 36, 45, 72 = 3x 3 = 9

So required measure is 9 litre.
