Explanation:

To find all the factors of a number using a While loop, the logic is:

Logic:

  1. Definition of a Factor:
    • A factor of a number n is any number i such that n%i = 0
  2. Iterate Through Possible Factors:
    • Use a While loop to iterate from 1 to n (inclusive).
    • For each number i, check if it divides n without a remainder.
  3. Store or Print the Factors:
    • If i is a factor, print or store it in a list.
