Question

3 big drums contain 36 litres 45 litres and 72 litres of oil. What biggest measure can measure all the the different quantities exactly.

Answer 1

AnSwEr :-

• 9 litres.

GiVeN : -

• Three big drums contain 36 litres, 45 litres, and 72 litres.

To FiNd : -

• Biggest measure which can measure all three different quantities.

SoLuTiOn : -

We have to find Highest common factor or H. C. F for biggest measure for this three values .

Then,

36 = 2 × 2 × 3 × 3

45 = 3 × 3 × 5

72 = 2 × 2 × 2 × 3 × 3

H. C. F = 3 × 3 = 9

So the biggest measure to measure this three value is 9 litres.
