When Grandma was asked about her age she told her grandchildren the following:
-"If the age of the oldest of you will be added to the product of ages of the younger two,- you would get my current age."
The three boys, Alex, Bob and Cid, started their thinking, but only Bob, the middle child provided the correct answer and added:
"If we had to perform the above operations a year ago - we would be off by 14 years...
What were the boys' Grandma's ages, given Alex's age was a prime number?
