## What is Armstrong of a number?

An Armstrong number is a number such that the sum .

of its digits raised to the third power is equal to the number .

itself.

For example, 371 is an Armstrong number, since !.

## Is 1 a narcissistic number?

Since the number of digits is not equal to the power to which they are taken for such numbers, it is not a narcissistic number. The smallest numbers which are sums of any single positive power of their digits are 1, 2, 3, 4, 5, 6, 7, 8, 9, 153, 370, 371, 407, 1634, 4150, 4151, 8208, 9474, …

## Is zero an Armstrong number?

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.

## Is 1 a prime number?

I was surprised because among mathematicians, 1 is universally regarded as non-prime. The confusion begins with this definition a person might give of “prime”: a prime number is a positive whole number that is only divisible by 1 and itself. The number 1 is divisible by 1, and it’s divisible by itself.

## Why is three the perfect number?

Three is the smallest number we need to create a pattern, the perfect combination of brevity and rhythm. It’s a principle captured neatly in the Latin phrase omne trium perfectum: everything that comes in threes is perfect, or, every set of three is complete. … We can use the rule of three to powerful effect.

## What is Armstrong number in C?

An Armstrong number of a three-digit number is a number in which the sum of the cube of the digits is equal to the number itself. Hence 153 is an Armstrong number.

## Why 7 is the perfect number?

Seven is the number of completeness and perfection (both physical and spiritual). It derives much of its meaning from being tied directly to God’s creation of all things. … The word ‘created’ is used 7 times describing God’s creative work (Genesis 1:1, 21, 27 three times; 2:3; 2:4).

## Is 125 an Armstrong number?

An Armstrong number is one where the sum of the cube of each digit of the number is equal to the number itself. For example, consider 153. Here the cube of 1 = 1; cube of 5 = 125 and cube of 3 = 27. … Some other Armstrong numbers are: 370, 371, 407.

## How do you know if a number has the same number?

Given two integers A and B, the task is to check whether both the numbers have equal number of digits. Approach: While both the numbers are > 0, keep dividing both the numbers by 10. Finally, check if both the numbers are 0.

## What are strong numbers?

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.

## Is 5 A Armstrong number?

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, … (OEIS A005188). … (OEIS A101337).

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

A number is called as Armstrong number if sum of cubes of digits of number is equal to the number itself. In the below C program, we are checking whether the input number is Armstrong or not. As you can see that sum of digits of number 370 is equal to the number itself.

## How many Armstrong numbers are there between 1 and 1000?

An Armstrong number is an n-digit base b number such that the sum of its (base b) digits raised to the power n is the number itself. Hence 153 because 13 + 53 + 33 = 1 + 125 + 27 = 153. Here is source code of the C Program to print armstrong number from 1 to 1000.

## 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.

## Why is 28 the perfect number?

A number is perfect if all of its factors, including 1 but excluding itself, perfectly add up to the number you began with. 6, for example, is perfect, because its factors — 3, 2, and 1 — all sum up to 6. 28 is perfect too: 14, 7, 4, 2, and 1 add up to 28.

## What is the weirdest number?

Examples. The smallest weird number is 70. Its proper divisors are 1, 2, 5, 7, 10, 14, and 35; these sum to 74, but no subset of these sums to 70. The number 12, for example, is abundant but not weird, because the proper divisors of 12 are 1, 2, 3, 4, and 6, which sum to 16; but 2 + 4 + 6 = 12.

## 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.
