 # Why Is The Number 1729 Special?

## Why 1729 is a magic number?

It is 1729.

Discovered by mathemagician Srinivas Ramanujan, 1729 is said to be the magic number because it is the sole number which can be expressed as the sum of the cubes of two different sets of numbers.

Ramanujanâ€™s conclusions are summed up as under: 1) 10 3 + 9 3 = 1729 and 2) 12 3 + 1 3 = 1729..

## Why is 1728 a special number?

In mathematics It is the number of cubic inches in a cubic foot. 1728 occurs in the algebraic formula for the j-invariant of an elliptic curve. As a consequence, it is sometimes called a Zagier as a pun on the Gross–Zagier theorem. The number 1728 is one less than the Hardy–Ramanujan number 1729.

## Is 1729 a perfect cube?

1729 = 13 + 123 = 93 + 10. The quotation is sometimes expressed using the term “positive cubes”, since allowing negative perfect cubes (the cube of a negative integer) gives the smallest solution as 91 (which is a divisor of 1729): 91 = 63 + (−5)3 = 43 + 3….1729 (number)← 1728 1729 1730 →Hexadecimal6C11611 more rows

## What is greatest and smallest number?

We know that a four digit number has four places, i.e., thousands, hundreds, tens and ones or units from left to right as Th, H, T, O. If greatest to lowest digits are placed at these places in descending order, we get the greatest number and if placed in ascending order, we get the smallest number.
