Abstract: Let p be an odd prime. The "first factor" $ {h^\ast}(p)$ of the class number of the field of pth roots of unity has been the subject of many investigations beginning with Kummer (1861). In the present paper it is shown how the theory of a function introduced by T. A. Pierce (1917) can be used to find the prime factors of $ {h^\ast}(p)$.
