Dear Sir/ Madame,
Is there a way of using a ray in a machine to determine the factors of a number ? For example, can a machine be calibrated to '87' and then some how reveal '29' and '3' as the factors.

Also, is there machine design that would be able to factorise very large numbers without having to rely on an impossibly accurate design. For example, a machine may be able to 'zoom' in on the factor by re-calibrating the machine over an increasingly small amount but over the same physical area, thereby not relying on the measurment of an extremely small angle/space.

Thank you for your time ! :)
