  We define an \emph{entropy product function}~(EPF) for
Taub-Newman-Unti-Tamburino~(TNUT) black hole~(BH) following the prescription
suggested by Wu et al.~\cite{wu} ~[PRD 100, 101501(R) (2019)]. The prescription
argues that a generic four-dimensional TNUT spacetime might be expressed in
terms of three or four different types of thermodynamic hairs. They can be
defined as the Komar mass~($M=m$), the angular momentum~($J_{n}=mn$), the
gravitomagnetic charge ($N=n$), the dual~(magnetic) mass $(\tilde{M}=n)$.
Taking this prescription and using the \emph{EPF}, we derive the \emph{central
charges} of dual CFT~(conformal field theory) via Cardy's formula. Remarkably,
we \emph{find} that for TNUT BH there exists a relation between the
\emph{central charges and EPF} as $c=6\left(\frac{\partial {\cal F}}{\partial
{\cal N}_{i}}\right)$, where ${\cal F}$ is EPF and ${\cal N}_{i}$ is one of the
integer-valued charges i.e. the NUT charges~($N$) or any new conserved
charges~($J_{N}$). We reverify these results by calculating the exact values of
different thermodynamic parameters. We define the EPF~${\cal F}$ from the first
law of thermodynamics of both horizons. Moreover, we write the first laws of
both the horizons for left-moving and right-moving sectors. Introducing the
B\'{e}zout's identity, we show that for TNUT BH one can generate more
holographic descriptions described by a pair of integers $(a,b)$. More
holographic pictures have a great significance in understanding the holographic
nature of quantum gravity. Furthermore, using the \emph{EPF} we derive the
central charges for Reissner-Nordstr\"{o}m-NUT~(RNNUT) BH, Kerr-Taub-NUT~(KNUT)
BH and Kerr-Newman-NUT~(KNNUT) BH. Finally, we prove that they are equal in
both sectors provided that the EPF is mass-independent~(or universal).
