Example Input Input number: 371 Output 371 is armstrong number An Armstrong number is a n-digit number that is equal to the sum of the nth power of its digits. For example –6 = 61 = 6371 = 33 + 73 + 13 = 371
Example Input Input any number: 10 Output Prime factors of 10: 2, 5
Example Input Input lower limit: 1 Input upper limit: 20 Output Prime numbers between 1-20: 2, 3, 5, 7, 13, 17, 19 Program to print prime numbers in given range
Example Input Input any number: 17 Output 17 is prime number Prime numbers are the positive integers greater than 1 that is only divisible by 1 and self. For example: 2, 3, 5, 7, 11 etc…
Example Input Input number1: 12 Input number2: 30 Output LCM = 60 LCM is a smallest positive integer that exactly divides two or more numbers. For Example
Example Input Input first number: 12 Input second number: 30 Output HCF of 12 and 30: 6 HCF (Highest Common Factor) is the greatest number that divides exactly two or more numbers. HCF is also known as GCD (Greatest Common Divisor) or GCF (Greatest Common Factor).
