Niven's constant

Définition(s)

In number theory, Niven's constant, named after Ivan Niven, is the largest exponent appearing in the prime factorization of any natural number n "on average". More precisely, if we define H(1) = 1 and H(n) = the largest exponent appearing in the unique prime factorization of a natural number n > 1, then Niven's constant is given by

${\\displaystyle \\lim _{n\ o \\infty }{\ rac {1}{n}}\\sum _{j=1}^{n}H(j)=1+\\sum _{k=2}^{\\infty }\\left(1-{\ rac {1}{\\zeta (k)}}\ ight)=1.705211\\dots }$

where ζ is the Riemann zeta function.
