the highly composite number ‘a30’

a30 := primorial(42681)*primorial(151)*primorial(29)*primorial(11)
      *primorial(7)*primorial(5)*primorial(4)*(primorial(3)^2)
      *(primorial(2)^4)*(primorial(1)^9);

? 10000*Qr(a30)
%370 = 9999.10909330009471428528222805072598431749321026349669841

Qr(W) = sigma(W)/(harmonic(W)+log(harmonic(W))*exp(harmonic(W)))

harmonic(Z)=Euler+psi(Z+1)

primorial(W)=prod(Z=1,W,prime(Z))
