4X4 grid – gcd from 1 to 24

 
 
To place distinct integers in a   n × n   grid such that all gcds from   1   to   2*n(n-1)   are generated.
 

If   n = 4,   then find 16 integers such that all gcds from   1 to   2*4(4-1) = 24 are generated
 
grid-gcd-2

 
Determine the integers so that the sum   A+B+C+…+N+O+P   is minimal
