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

Brenda O'Malley is home making dinner, as usual, when Tim Finnegan arrives at her door.
"Brenda, may I come in?" he asks. "I've somethin' to tell ya".
"Of course you can come in, you're always welcome, Tim. But where's my husband?"
"That's what I'm here to be telling ya, Brenda. There was an accident down at the Guinness brewery..."
"Oh, no!" cries Brenda. "Please don't tell me."
"I must, Brenda. Your husband Shamus is dead and gone. I'm sorry."
Finally, she looked up at Tim. "How did it happen, Tim?"
"It was terrible, Brenda. He fell into a vat of Guinness Stout and drowned."
"Oh my dear! But you must tell me truth, Tim. Did he at least go quickly?"
"Well, Brenda... no. In fact, he got out three times to pee."
