# Come on, have a cup of tea

**Number Theory**Level 3

Dhudhnath has two vessels containing \(720\text{ ml}\) and \(405\text{ ml}\) of milk respectively.

Milk from these containers is poured into glasses of equal capacity to their brim, but the milk from the two different vessels (\(720\text{ ml}\) and \(405\text{ ml}\)) can not be poured together in a single glass. They have to be poured separately into glasses of equal capacity.

Find the minimum number of glasses that can be filled.
