Do you remember prime numbers? They are numbers that are not
divisible by any other number. The series starts this way
2, 3, 5, 7, 11, 13…
and goes on forever. All whole numbers can be broken down into
the prime numbers that make them up. For example, 66 can be broken
down to 2*3*11. It cannot be broken down any further. So 66 is made
up of the first prime number(2) times the second prime number
(3)times the fifth prime number(11). We can refer to the first
prime number as P(1), the second as P(2) and so on. In other
words:
66 = 2 * 3 * 11 = P(1) * P(2) * P(5)
The coordinates of this geocache are as follows:
P(1) * P(3) * P(3) * P(9) * P(11) * P(28)
P(15) * P(19) * P(537)
