Let p be a prime number and n be a positive integer, then exponent of p in $n!$ is denoted by ${\mathrm{E}}_{\mathrm{p}}(\mathrm{n}!)$ and is given by ${\mathrm{E}}_{\mathrm{p}}(\mathrm{n}!)=\left[\frac{\mathrm{n}}{\mathrm{p}}\right]+\left[\frac{\mathrm{n}}{{\mathrm{p}}^2}\right]+\left[\frac{\mathrm{n}}{{\mathrm{p}}^3}\right]+\dots \dots +\left[\frac{\mathrm{n}}{{\mathrm{p}}^{\mathrm{k}}}\right]$ where ${\mathrm{p}}^{\mathrm{k}}<\mathrm{n}<{\mathrm{p}}^{\mathrm{k}+1}$ and [x] denotes the integral part of x. If we isolate the power of each prime contained in any number N, then N can be written as $\mathrm{N}=2^{{\mathrm{\alpha }}_1}\cdot 3^{{\mathrm{\alpha }}_2}\cdot 5^{{\mathrm{\alpha }}_3}\cdot 7^{{\mathrm{\alpha }}_4}$…. where ${\alpha }_i$ are whole numbers.
