Question: Lucky fall
George and Harry enjoy creating and solving puzzles. They also enjoy playing card games. On one occasion, George was shuffling the cards, a standard deck, when three cards fell out and landed face-down on the table. George picked up the cards and was about to return them to the deck when he noticed an interesting fact about them.
He said, "I have three cards here, Harry. As luck would have it, if I take the numerical value of each card and multiply the three values together, the result equals my lucky number. The highest card is a seven. What are the other two cards?"
Harry considered the problem for a few seconds and replied, "I suppose that an ace has a value of one, so each of your other two cards has a value lower than seven and possibly as low as one, right?"
"Right," confirmed George.
"Well," added Harry, "you haven't told me what your lucky number is, so I could only guess what the two cards are. I need more information to work it out."
"I see your difficulty," replied George, "so I will give you one more clue: the lowest card is a spade."
Harry pondered the problem again for a while, and then correctly identified the two cards.
What were they?
