Who invented Kaprekar number?
In 1949, Kaprekar discovered an interesting property of the number 6174, which was subsequently named the Kaprekar constant. He showed that 6174 is reached in the limit as one repeatedly subtracts the highest and lowest numbers that can be constructed from a set of four digits that are not all identical.
What is the contribution of D. R. Kaprekar?
There he excelled, winning the Wrangler R P Paranjpe Mathematical Prize in 1927. This prize was awarded for the best original mathematics produced by a student and it is certainly fitting that Kaprekar won this prize as he always showed great originality in the number theoretic questions he thought up.
When did D. R. Kaprekar died?
1986D. R. Kaprekar / Date of death
Why is 4 a unique number?
Every number has its on speciality or it has some unique properties. The properties of some Unique Numbers are given below. 4 is the only composite number n which doesn’t divide (n-1)!
Who is known as father of geometry?
Euclid, The Father of Geometry.
What is the 1089 Trick?
Write down a three-digit number whose digits are decreasing. Then reverse the digits to create a new number, and subtract this number from the original number. With the resulting number, add it to the reverse of itself. The number you will get is 1089!

What is the contribution of Kaprekar in number theory?
Working largely alone, Kaprekar discovered a number of results in number theory and described various properties of numbers. In addition to the Kaprekar’s constant and the Kaprekar numbers which were named after him, he also described self numbers or Devlali numbers, the harshad numbers and Demlo numbers.
What are some of the most interesting mathematical patterns discovered by Kaprekar?
Kaprekar is remembered today for a range of curious mathematical patterns that he discovered. The best known is probably that related to the number 6174, sometimes called Kaprekar’s constant. If we take the four digits of 6174 and form two new numbers by arranging them in descending and ascending order, we get 7641 and 1467.
What is Kaprekar’s constant?
Kaprekar showed that in the case of 4-digit numbers in base 10, if the initial number has at least two distinct digits, after 7 iterations this process always yields the number 6174, which is now known as Kaprekar’s constant. . This is the first number of the sequence.
What is Kaprekar’s routine?
In number theory, Kaprekar’s routine is an iterative algorithm that, with each iteration, takes a natural number in a given number base, creates two new numbers by sorting the digits of its number by descending and ascending order, and subtracts the second from the first to yield the natural number for the next iteration.
