"Mathematicians have tried in vain to this day to discover some order in the sequence of prime numbers, and we have reason to believe that it is a mystery into which the human mind will never penetrate." Leonhard Euler
I am fascinated by numbers, particularly prime numbers. When my age is a prime number, I always joke about being in my “prime”. Today is Kimmie’s birthday and she is now 29 years old, the tenth time she has been in her “prime”. A few days ago, I turned 61. Dylan and my sister Denise each reached a prime age earlier in August. Arun hit another prime in February when he turned 53. Realizing we all had turned prime ages in 2017 (also a prime number), I wondered if this had ever happened before.
To find out, I made a table listing Dylan’s and Kimmie’s prime ages and added in the three older relatives. The highlighted numbers are the prime numbers.
As you can see, this is the first year that we have each reached a prime age! I will leave it to Dylan to write a program to find out the next time this will happen.
