Question 321146
He died in the year 2000. 
The year of his birth is the product of 2 prime numbers.
 One of these prime numbers is the smallest 3-digit prime number.
 What is the sum of the digits that make up the year of his birth?
:
The sum of the two prime numbers = 120
Because:
101 is the smallest 3 digit prime number
:
A good guess would be that 19 is the other prime number
:
19 * 101 = 1919, is the year he was born
:
The prime above and below 19, 17 & 23 would not be possible
