Which number is the Kaprekar constant for 4-digit numbers?
The Kaprekar constant is 6174. It is the result of a process where you subtract the smallest possible number from the largest possible number formed by the digits of a four-digit number and repeat the process until the result is 6174. This constant appears in various number-based puzzles.
In this chapter students explore the world of numbers. They learn about number patterns and various operations like addition subtraction multiplication and division. The chapter also introduces concepts like factors multiples prime numbers and divisibility rules. Understanding these concepts helps build strong mathematical reasoning and problem-solving skills.

This number is known as the Kaprekar constant for 4-digit numbers. Whenever you take a number with four digits (having at least two different digits), write down this number in decreasing and increasing order, form two numbers, subtract the smaller number from the larger number, repeat this process for many times and eventually you’ll arrive at the number 6174. When this process is repeated, then always the outcome is 6174.
