On the last digit and the last non-zero digit of $n^{n}$ in base $b$

José María Grau, Antonio M. Oller-Marcén

In this paper we study the sequences defined by the last and the last non-zero digits of $n^{n}$ in base $b$ . For the sequence given by the last digits of $n^{n}$ in base $b$ , we prove…

An $O ~ (lo g^{2} (N))$ time primality test for Generalized Cullen Numbers

Jose Maria Grau, Antonio M. Oller-Marcen

Generalized Cullen Numbers are positive integers of the form $C_{b} (n) := n b^{n} + 1$ . In this work we generalize some known divisibility properties of Cullen Numbers and present two prima…

On the base $b$ expansion of the number of trailing zeroes of $b^{k}!$

Antonio M. Oller-Marcen, Jose Maria Grau

Let us denote by $Z_{b} (n)$ the number of trailing zeroes in the base b expansion of $n!$ . In this paper we study the connection between the expression of $\vartheta(b):=\lim_{n\to…
