## What are the Armstrong numbers between 1 to 500?

An Armstrong number of is an integer such that the sum of the cubes of its digits is equal to the number itself. The Armstrong numbers between 1 to 500 are : 153, 370, 371, and 407.

## What is Armstrong value?

Armstrong number is a number that is equal to the sum of cubes of its digits. For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers. Let’s try to understand why 153 is an Armstrong number.

## What is the logic of Armstrong number in C?

Check Armstrong Number of n digits. Enter an integer: 1634 1634 is an Armstrong number. In this program, the number of digits of an integer is calculated first and stored in n . And, the pow() function is used to compute the power of individual digits in each iteration of the second for loop.

## Is 28 a perfect number?

Perfect number, a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3. Other perfect numbers are 28, 496, and 8,128.

## How do I find my 4 digit Armstrong number?

C program to check Armstrong number using functionint check_armstrong(long long); long long power(int, int);int main () { long long n;printf(“Input a number\n”); scanf(“%lld”, &n);if (check_armstrong(n) == 1) printf(“%lld is an armstrong number.\ … return 0; }int check_armstrong(long long n) { … t = n;while (t != 0) {More items…

## What is a palindrome with numbers?

A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number that remains the same when its digits are reversed. Like 16461, for example, it is “symmetrical”. … The palindromic primes are 2, 3, 5, 7, 11, 101, 131, 151, … (sequence A002385 in the OEIS).

## What is strong number?

Strong number is a number whose sum of all digits’ factorial is equal to the number ‘n’. Factorial implies when we find the product of all the numbers below that number including that number and is denoted by ! (Exclamation sign), For example: 4! = 4x3x2x1 = 24.

## What is Armstrong Number example?

In case of an Armstrong number of 3 digits, the sum of cubes of each digit is equal to the number itself. For example: 153 = 1*1*1 + 5*5*5 + 3*3*3 // 153 is an Armstrong number.

## How many Armstrong numbers are there?

th powers of their digits (a finite sequence) are called Armstrong numbers or plus perfect number and are given by 1, 2, 3, 4, 5, 6, 7, 8, 9, 153, 370, 371, 407, 1634, 8208, 9474, 54748, …
