The number 1729 is known by the name the 'Hardy-Ramunajan number'. The famous British mathematician G. H. Hardy was quoted as saying '"I remember once going to see him when he was ill atPutney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavorable omen. "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."'

ramanujam expressed the number 1729 in sum of cubes of two positive numbers in two different ways.
1729
1^3+12^3=9^3+10^3
ramanujan's pet number is 1729(one thousand seven hundred twenty-nine)
(9*9*9) + (10*10*10)= 1000+729=1729
1729
Ramanujan number is the smallest natural number that can be can be expressed as a sum of two perfect cubes in two different ways:- 123 + 13 = 1728+1 =1729 103 + 93 = 1000+729 =1729
1729 is the Ramanujan's favorite number because 1729 is the sum of two consecutive cubes. 12³+1³ 1728+1= 1729 10³+9³ 1000+729= 1729

ANSWER: 1729 is a composite number.It is divisible by 7.
1729 is the smallest natural number that can be expressed as a sum of two cubes of positive number in two different ways: 1729 = 13 + 123 = 93 + 103 It is known as the Ramanujan-Hardy number. But is also known as a Taxicab number which are numbers that can be expressed as sums ot 2 cubes in 2, 3, 4, etc different ways.

No, it is not a prime number.
1+7+2+9=19 19*91=1729 that's why its ramanujam number
