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

Subway Party
Two small-town merchants were visiting New York City for the first time to attend a conference.
There was a large party thrown, with lots of food and drink. At the end of the party, they both staggered outside.
One guy crossed the street, while the other stumbled into a subway entrance.
When the 1st guy reached the other side of the street, he noticed the other emerging from the subway stairs.
"Where ya been?"
he slurred.
"I don't know," gushed the other guy, "but you should see the train set that guy has in his basement!"
