What is the smallest positive integer that has exactly 40 divisors?

 

\(\sigma_0(1680) = 40\)

 

See  http://oeis.org/search?q=sigma_0&sort=&language=german&go=Suche

See table of n, a(n) for n = 1..100000: http://oeis.org/A000005/b000005.txt

 

The smallest positive integer that has exactly 40 divisors is 1680
