👉 Armstrong's number, or the Armstrong number, is a special sequence of digits where a number is equal to the sum of its own digits each raised to the power of the number of digits. For example, 153 is an Armstrong number because 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153. To find an Armstrong number, you can calculate the sum of each digit raised to the power of the total number of digits in the number. For instance, for a 3-digit number n = d
10^2 + e
10^1 + f
10^0, the Armstrong number condition is d^3 + e^3 + f^3 = n. This unique property makes Armstrong numbers intriguing for mathematical exploration and has been the subject of various computational challenges, including the famous "Armstrong's Number Problem," where the goal is to find the largest Armstrong number below a given limit.
