Geocache Description:

Consider this your introduction to the "BunkerDave Geocaching University." If you can figure out the puzzle and reach this cache, you deserve some recognition. I should probably tell you - the puzzle is the easy part.
THE POSTED COORDS ARE IN THE MIDDLE OF UTAH LAKE. YOU CAN GO SWIMMING IF YOU LIKE, BUT THERE IS NO CACHE THERE

THE POSTED COORDS ARE NOT THE CACHE COORDS. YOU MUST SOLVE THE PUZZLE TO GET THE CACHE COORDS

The completed puzzle uses numbers 1 through 16. Each number is used once.
In the NW, there are four consecutive numbers. D-L=L
The SW only has single digit prime numbers. E-F=K
E is two times M, which is two times B. F-M=J
The NE full of even numbers. P is odd.
The SE contains only two digit numbers. F-M=J
D is the only two digit number in the NE. G-C=C
The sum of the NE is two times F.

When you get the puzzle solved, you just need to do a little simple math:
O-(I*C) = A*,M*,N*
G-F+I = B*,C*,D*
H-(K*A) = E*,F*,L*
D-C = G*
K-A = H*,I*,J*
G/C = K*,O*

Plug the resulting numbers into the following format:

N A*B*° C*D*.E*F*G*
W H*I*J*° K*L*.M*N*O*


This is DD° MM.MMM format, so if you put the numbers in order corresponding to their letter, you will have the coordinates.
Thanks to Fractal for the puzzle and graphic.
