so yeah the lowest value..... well start off by listing all the possible pairs that have a product of 192

I would break it down into prime numbers, and then use the entire list of prime numbers and multiply them together to make two numbers that make up 192. Then after a few you should have all of the numbers that could make up in a chart, and you can pick the two that add up to make the lowest number.

x times y =192$\rightarrow$ y=192/x x+y=s $\rightarrow$ x+(192/x)=s ,, and then dervive both sides when you know s is a constant you get x=$\sqrt{192}$ is a local and absolute minimum
