Jones Factorization by Period Proxy (~ 1965) used the intrinsic nature of period
that is the heart of Shor's algorithm for factoring using quantum computers.
Finding the period can be solved using asyncronous parallel processors.
p(a) = period of 1/a
if x=ab : p(x) = p(a) * p(b)
Jones provides an algorithm for tickling out a and b and hints that there are other proxies that can be used.
