There are four three-digit numbers that share this property: the number itself, its double and its triple contain each digit from 1 to 9 exactly once. For example, 192 is one of them because 192, 384, 576 contain 1 to 9 each once. 273 is another one of them because 273, 546, 819 contain 1 to 9 each once. Can you find the other two numbers and calculate the product of these two numbers?Correct answers: 23

Morty and Saul, are out one afternoon on a lake when their boat starts sinking.
Saul the banker says to Morty, "So listen, Morty, you know I don't swim so well." Morty remembered how to carry another swimmer from his lifeguard class when he was just a kid. So Morty is begins tugging Saultoward shore. After twenty minutes, he begins to tire.
Finally about 50 feet from shore, Morty asks Saul, "So Saul, do you suppose you could float alone?"
Saul replies, "Morty, this is a hell of a time to be asking for money!"
