This is apparently the smallest solution.
The derivation of the solution itself requires an understanding of Diophantine equations and elliptical curves, which I will not pretend to understand well enough to summarize.
Electronic engineers will know that 1, 1, 8 is closer but will go for 1, 1, 6.8 because they are in the E6 series and that will save 0.1 cents per device.
I have to admit, my solution is not correct anyways. I simple found a "solution" for which the margin of error is smaller than the calculator's level of precision.
