Isn’t that kind of a thing it needs to do to find the factorials of large numbers to break traditional encryption?

Not really. It needs to apply unitary operators to elements in Hilbert space, which is essentially multiplying matrices onto vectors.
Which you could do by multiplying the involved numbers one by one, as most classical methods would, but then you’re missing the point of using a quantum computer.
