## What is Harshad number in C?

C program to determine whether the given number is a Harshad Number. If a number is divisible by the sum of its digits then it will be known as a Harshad Number. For example: The number 156 is divisible by the sum (12) of its digits (1, 5, 6 ).

## What are Disarium numbers?

A number is called Disarium if sum of its digits powered with their respective positions is equal to the number itself.

## How do you find Automorphic numbers?

In mathematics, an automorphic number is a number whose square “ends” in the same digits as the number itself. For example, 52 = 25, 62 = 36, 762 = 5776, and 8906252 = 793212890625, so 5, 6, 76 and 890625 are all automorphic numbers.

## Why 1 is a special number?

The number one is far more special than a prime! It is the unit (the building block) of the positive integers, hence the only integer which merits its own existence axiom in Peano’s axioms. … It is the only perfect nth power for all positive integers n. It is the only positive integer with exactly one positive divisor.

## 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.

## What is palindrome number?

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”.

## What is Harshad number in Java?

Java Numbers: Exercise-12 with Solution In recreational mathematics, a harshad number in a given number base, is an integer that is divisible by the sum of its digits when written in that base. Example: Number 200 is a Harshad Number because the sum of digits 2 and 0 and 0 is 2(2+0+0) and 200 is divisible by 2.

## What is special number?

A number is known as Special number when sum of the factorial of digits is equal to the original number (given number). Examples: Below are examples of numbers which are Special. Number to check : 145 1! + 4!

## Is 51 a Harshad number?
