Backtracking Approach for Factor Combinations

  1. Define a helper function backtrack that takes the current list of factors and the current product.
  2. If the current product is 1 and the list of factors has more than one element, add the list to the result (since we've found a valid combination).
  3. Iterate over possible factors starting from the last factor in the list or 2 if the list is empty, up to the square root of the current product.
  4. For each factor i, if it divides the current product, recursively call backtrack with the current list plus i and the new product divided by i.
  5. Continue the process until all combinations are found.
