Let F ( x ) be an irreducible polynomial with integer coefficients and degree at least 2. For x ⩾ z ⩾ y ⩾ 2 , denote byH F ( x , y , z )the number of integers n ⩽ x such that F ( n ) has at least one divisor d with y < d ⩽ z . We determine the order of magnitude ofH F ( x , y , z )uniformly for y + y / log C y < z ⩽ y 2and y ⩽ x 1 − δ, showing that the order is the same as the order of H ( x , y , z ) , the number of positive integers n ⩽ x with a divisor in ( y , z ] . Here C is an arbitrarily large constant and δ > 0 is arbitrarily small.
