Python Code to Print Factors of a Given Number Using a While Loop

Write a python program to print the factors of a given number using a while loop:

This code will print all the factors of a given number using a while loop.

Simple code:

num = int(input("Enter a number: "))
i = 1

while(i <= num):
    if(num % i == 0):
        print(i)
    i += 1

Code with explanation:

# Ask the user to enter a number and store it in the variable 'num'
num = int(input("Enter a number: "))

# Initialize a variable 'i' to 1
i = 1

# Use a while loop to iterate through all the numbers from 1 to 'num'
while(i <= num):
    # Check if the current number is a factor of 'num' using the modulus operator
    if(num % i == 0):
        # If it is a factor, print it
        print(i)
        
    # Move to the next number
    i += 1

Explanation:

• The program prompts the user to enter a number using the input() function and stores it in the variable ‘num’.
• A while loop is used to iterate through all the numbers from 1 to ‘num’ (inclusive). At each iteration, the current number is checked if it is a factor of ‘num’ using the modulus operator. If it is a factor, it is printed using the print() function.
• Finally, the loop moves to the next number by incrementing the ‘i’ variable by 1.
