### Ramanujan Number

One of his notable achievements includes the discovery of what are now known as “Ramanujan numbers,” which are specific integers characterized by unique mathematical properties.

• Ramanujan numbers are special numbers named after the famous Indian mathematician Srinivasa Ramanujan.
• These numbers have a cool property: they’re the smallest numbers that can be made by adding two cubes together in two different ways.
• Imagine you have two cubes, and if you add up the numbers inside each cube, you get a Ramanujan number.
• Let’s take the example of 1729, which is the first Ramanujan number. It’s special because you can make it by adding up two sets of cubes differently: 13+12313+123 and 93+10393+103.
• Finding Ramanujan numbers can not be easy to find, but when they do find them, it’s exciting because they’re pretty rare.
• These numbers are not just interesting because of their uniqueness, but they also have important uses in math.
• Ramanujan numbers appear in various areas such as number theory, algebra, and even in cryptography to secure information. Simply put, they’re like hidden gems in the world of math. These special numbers demonstrate the fascinating and unexpected aspects of mathematics.
