Mar 19, 2024 · In this Python tutorial, you learned how to write a program to find perfect number in Python. You learned what perfect numbers are, and then, using three different examples, you wrote a program that can find the perfect number using loops, functions, and recursion.

Feb 26, 2025 · A Perfect Number is a positive integer that is equal to the sum of its proper divisors, excluding the number itself. Example: 6 is a perfect number because its divisors (excluding itself) are 1, 2, and 3, and their sum is 6 (1 + 2 + 3 = 6).

How to write a Python program to find Perfect Number using For Loop, While Loop, and Functions. Any number can be the perfect number if the sum of its positive divisors excluding the number itself is equal to that number. For example, 6 is a perfect number in Python because 6 is divisible by 1, 2, 3, and 6.

Oct 24, 2018 · In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also known as its aliquot sum). The first perfect number is 6. The next perfect number is 28. This is followed by the perfect numbers 496 and 8128.

Here is source code of the Python Program to check if a number is a Perfect number. The program output is also shown below. 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!") 1. User must enter the number and store it in a variable. 2.

Mar 31, 2025 · Below are the steps to find a perfect number in Python: Set number or take an integer number as input from the user. Initialize a variable divisors_sum to 0. This variable will store the sum of all proper divisors. Iterate through the …

Apr 25, 2020 · In this Python program, we will learn how to find or print the perfect number between 1 to 1000 or between a specific range. What is a Perfect Number? A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself.

Mar 6, 2024 · This method involves iterating through all possible divisors of the input number and accumulating their sum. If the sum of divisors matches the original number, it is perfect. Here’s an example: def is_perfect_number(num): sum_of_divisors = 0 for i in range(1, num): if num % i == 0: sum_of_divisors += i return sum_of_divisors == num print(is ...

Jan 9, 2022 · To check for a perfect number, we will first find its factors. After that, we will check if the sum of all the factors is double the given number or not. To find the factors of the given number N, we will divide the number by all the numbers starting from 1 to N.

Jun 28, 2023 · Trial Division: By dividing the number by smaller numbers and checking the remainder, we can identify perfect numbers. Let’s explore two example implementations of perfect number identification in Python, using the brute force method and the Euclid-Euler theorem.
