Abstract: Let be the least common multiple of a random set of integers obtained from by retaining each element with probability independently of the others. We prove that the process , after centering and normalization, converges weakly to a certain Gaussian process that is not Brownian motion. Further results include a strong law of large numbers for as well as Poisson limit theorems in regimes when depends on in an appropriate way.
