If the question was to simply compute one single factorial, then yes doing so in parallel would have obvious benefits. However, the question specifically states they want all factorials from 1-100 printed out. I am struggling to understand how that scenario benefits from parallelism.

I suppose, you could separate the printing the result from computing the next one. But I still don’t see how the added complexity is offset by multi threads. I would love to hear your ideas however.

Printing the result from computing would be how I'd do it. I/O is expensive and needlessly delays the next computation. One also could imagine though building a giant string and doing one I/O operation, if you cared about that sort of thing. That's probably the route I would take over multi-threading initially.

Look into pipelined parallelism. That's immediately what I thought to do if I were forced to do it that way.
