Display Armstrong Numbers Between 1 to 1000 using a Loop
The simplest approach to finding Armstrong numbers is using a loop to iterate through each number from 1 to 1000 and check if it is an Armstrong number.
Javascript
function isArmstrong(number) { let sum = 0; let temp = number; const digitsCount = number.toString().length; while (temp > 0) { let digit = temp % 10; sum += Math.pow(digit, digitsCount); temp = Math.floor(temp / 10); } return sum === number; } // Driver code let N = 1000; for (let i = 1; i <= N; i++) { if (isArmstrong(i)) { console.log(i); } } |
Output
1 2 3 4 5 6 7 8 9 153 370 371 407
JavaScript Program to Display Armstrong Numbers Between 1 to 1000
Armstrong number is a number equal to the sum of its digits raised to the power 3 of the number of digits. For example, 153 is an Armstrong number because 1^3 + 5^3 + 3^3 = 153. This article will explore how to find Armstrong numbers between 1 to 1000 using JavaScript.
