The present-day trend of the numerical coding of chemical structures with topological indices (TIs) has established quite successful in medicinal chemistry and bioinformatics. This strategy provides the annotation, comparison, rapid collection, mining, and retrieval of chemical structures within large databases. Afterward, TIs can be used to look for quantitative structure-activity relationships and quantitative structure-property relationships, which are models that associate chemical structure with biological activity. In these analyses, degree-based TIs have secured a significant place among the different types of descriptors because of the ease of generation and the momentum with which these computations can be executed. In this paper, we compute the lower and upper bounds of the first, second, and third Zagreb, the first and the second multiple Zagreb, the geometric-arithmetic, the general sum connectivity, the general Randi$\acute {c}$, the atom-bond connectivity, the augmented Zagreb, and the harmonic indices of the corona product of$F$-sum of connected graphs in the form of their factor graphs by applying combinatorial inequalities.
