Explanation:<\/h2>\n\n\n\n
The program prints all numbers that divide num<\/code> evenly, which are its factors.<\/p>\n\n\n\n
Variables:<\/strong><\/p>\n\n\n\n
num<\/code>: Stores the number entered by the user.<\/p>\n\n\n\n
i<\/code>: Loop variable used to check divisibility.<\/p>\n\n\n\n
User Input:<\/strong><\/p>\n\n\n\n
The user is prompted to enter a number, which is stored in num<\/code>.<\/p>\n\n\n\n
Loop to Find Factors:<\/strong><\/p>\n\n\n\n
A for<\/code> loop runs from 1<\/code> to num<\/code>.<\/p>\n\n\n\n
For each i<\/code>, the program checks if num % i == 0<\/code>.<\/p>\n\n\n\n
If true, i<\/code> is a factor and is printed.<\/p>\n\n\n\n
Output:<\/strong><\/p>\n\n\n\n
Enter a positive integer: 28\nFactors of 28 are: 1 2 4 7 14 28<\/code><\/pre>\n
