Is 5 an Automorphic number?

An automorphic number is a number whose square ends with the number itself. For example, 5 is an automorphic number, 5*5 =25. The last digit is 5 which same as the given number. It has only a positive single digit number.

How do I find my 4 digit Armstrong number?

A number is thought of as an Armstrong number if the sum of its own digits raised to the power number of digits gives the number itself. For example, 0, 1, 153, 370, 371, 407 are three-digit Armstrong numbers and, 1634, 8208, 9474 are four-digit Armstrong numbers and there are many more.

What is Armstrong number?

How would check a number is Armstrong number using python?

Source code to check Armstrong Number of n digits

0; oriNum /= 10) remainder = oriNum % 10; // store the sum of the power of individual digits in the result result += pow(remainder, n); if ((int)result == numb) printf("%d is an Armstrong number.

Is 54748 An Armstrong number?

Likewise, 54748 is an Armstrong number of order 5 because 55 + 45 + 75 + 45 + 85 = 3125 + 1024 + 16807 + 1024 + 32768 = 54748. More generally, an n-digit number in base b is said to be a base b Armstrong number of order n if it equals the sum of the nt h powers of its base b digits.
