I would set up a SAAS site that lets people enter their integer and shows the factors. If the number is prime I would request payment before telling them that it’s prime, to monetize. I have previous relevant experience running is is isodd.dev and iseven.dev, two SAAS that tell if a number is odd or even. I think the bigger question is, if you had this factorizing tech, what stack would you use to implement it?
