Check my equations carefully to be sure they are correct.
But, it seems to work...
Anyway, it's an idea.


per =  24 # 2_400_000
(1..per-2).each do |a|
  c = (a.to_f**2+(per-a)**2)/(2*(per-a))
  b = per-a-c
  p [a,b.to_i,c.to_i] if a>=1 && b>=1 && c>=1 && b == b.to_i  # integers only
  #p [a,b,c] if a>=1 && b>=1 && c>=1  #include floats
end
