Two old college friends bump into each other one day at Stafford Street. They hadn't seen each other in over 20 years.
The first guy says to the second: "how have you been?"
Second: "Great! I got married and I have three daughters now"
First: "Really? how old are they?"
Second: "Well, the product of their ages is 72, and the sum of their ages is the same as the number on that building over there.."
First: "Right...ummm...oh wait, I still don't know"
second: "Oh sorry, the oldest one just started playing the piano"
First: "Wonderful! my oldest is the same age!"

QUESTION: How old are the daughters?
