Ramanujan replied that 1729 was not a boring number at all: it was a very interesting one. He explained that it was the smallest number that could be expressed by the sum of two cubes in two different ways. This story is very famous among mathematicians. 1729 is sometimes called the “Hardy-Ramanujan number”..
Likewise, what are Ramanujan numbers?
Ramanujan Numbers( preciously termed as Hardy-Ramanujan Numbers) are those numbers which are the smallest positive integers which can be represented or expressed as a sum of 2 positive integers in n ways.
Furthermore, which number represents Hardy Ramanujan number what is so unique about this number? 1729
Similarly, you may ask, what is special about the number 1729?
1729 is the natural number following 1728 and preceding 1730. It is known as the Hardy–Ramanujan number, after an anecdote of the British mathematician G. H. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways."
What is Hardy Ramanujan?
Hardy-Ramanujan Number. The smallest nontrivial taxicab number, i.e., the smallest number representable in two ways as a sum of two cubes. It is given by. The number derives its name from the following story G. H. Hardy told about Ramanujan.
