I got 1 either side of it easily enough: (9*6*2*5 -4 (536) and -2 again to get 534), however I was about to go to bed when the solution came to me

((2*4)+2)*6*9)-5= 535.

I can't get any closer - given that it's almost 2 days since it was posted, I'd say you (Spacecoyote) go ahead and pick the next puzzle.

Well done on that one - I was trying 24*37, 111*8 etc, never saw the 148*6 factor

I'd say go ahead and pick the next puzzle. I had 693 myself, but held off to see if anyone would solve it.
