What is a perfect number algorithm?
Algorithm to check Perfect number: Ask the user to enter an integer number. Initialize another variable with 0 to store the sum of proper positive divisors. Go through every number from 1 to n/2 and check if it is a divisor. Maintain the sum of all divisors.
How 28 is a perfect number?
The proper factors of 28 are 1, 2, 4, 7 and 14. The sum of proper factors is 28. According to the definition of perfect numbers, 28 is a perfect number. therefore, 28 is a perfect number.
Is perfect number python?
Here is source code of the Python Program to check if a number is a Perfect number. n = int(input(“Enter any number: “)) sum1 = 0 for i in range(1, n): if(n % i == 0): sum1 = sum1 + i if (sum1 == n): print(“The number is a Perfect number!”) else: print(“The number is not a Perfect number!”)
What is perfect number example?
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 perfect number in loop?
A Perfect Number is a number that is equal the sum of its positive divisors excluding the given Number. For example, 28 is a Perfect Number, because 28 is equal to the sum of its positive divisors (ie.
WHY IS 496 a perfect number?
Now, the sum of divisors of a number, excluding the number itself, is called its aliquot sum, so we can define a perfect number as one that is equal to its aliquot sum. Hence, the sum of these factors is equal to the given number. So, 496 is a perfect number.
Why is 4 the perfect number?
Numbers like 6 that equal the sum of their factors are called perfect numbers. 6 is the first perfect number . 4 is not a perfect number because the sum of its factors (besides 4 itself), 1+2, is less than 4. Numbers like 4 are known as deficient numbers .
