Abstract
A graph G = (V(G), E (G)) is observed to admit prime labeling when the vertices of the graph are labeled with unique integral values from [1,|V|] in a way that for every edge uυ the labels designated to u and υ share no common positive factors except 1. In this research article we investigate that the 3-shadow graphs of some star related graphs such as K1,n, B (n, n) and Spl(K1,n) admits prime labeling.
