a(n) = A002182(n) / A152047(n). [From Klaus Brockhaus, Nov 27 2008]

Links

Table of n, a(n) for n=1..55.

Example

a(9) = 10 because the ninth highly composite number is 60 and 10 is the smallest divisor of 60 >= sqrt(60). (Although 8 >= sqrt(60), 8 does not qualify because it is not a divisor of 60.)
