WebGiven s, r, n and α with s=nαand α>1/2, there are at most two positive divisors of n of the form(sx+r). Proof. The divisors ofnof the form (sx+r) are paired with those of the form (sy+r)wherer=n/r(mods), 0n1/2andx ≥1, then its corresponding factor must bes×0+r, and so there can be only one divisor with x ≥1, and one withx= 0. Web20 jan. 2024 · Example: How many divisors are there of the number 12? 12 = 2^2 x 3 The number 2 can be chosen 0 times, 1 time, 2 times = 3 ways. The number 3 can be chosen 0 times, 1 time = 2 ways. Putting these results together we have 3 x 2 = 6 ways of finding factors of 12. This is the same example we saw before.
