Geocache Description:


Lillico is a picturesque, flat coastal area between Bass Strait, the Don Heads, the Forth River and elevated land to the south. Many have dreamed of swapping residences with the long-standing farming families who live at Lillico. There have been a few attempts to rezone some of the rural land to residential but the attempts have been resisted very strongly by the resident families and members of the wider community who want to keep the prime location as pristine agricultural land on a unique coastal plain.

Musing about Lillico being a prime location led to musings about prime numbers. There are some interesting numbers that you get if you multiply a prime number whose digits add up to 10 by the largest possible other prime number such that the result remains no bigger than 1,000. There are only ten of them. 

Your task is to find the ten numbers and place them in order from the largest to the smallest.

Now let

  • third largest number = ABC
  • seventh largest number = DEF

where the letters A, B, C, D, E and F are single digits.

 

You will find the cache at

Happy Hunting. The cache is a 200mL cammoed sistema.
