Once Ramanujan, who was in London, was sick.

Hardy came to visit him in a Taxi.

 

This was the conversation

 

What are Hardy Ramanujan Numbers? - Part 2

That’s a very dull number

 

From then on,

number 1729 is known as Hardy-Ramanujan Numbers

 

1729 can be expressed as

  1729 = 1 + 1728 = 1 3 + 12 3

  Or

  1729 = 729 + 1000 = 9 3 + 10 3

 

Thus,

1729 is the smallest number that can be represented as sum of two cubes in two different ways
