Abstract
We determine, up to multiplicative constants, the number of integers that have no prime factor and a divisor in . Our estimate is uniform in . We apply this to determine the order of the number of distinct integers in the multiplication table which are free of prime factors , and the number of distinct fractions of the form with and .
