How do the suggestions in federalist 39 and federalist 46 allow the united states grow as a republic and still handle factionalism?

Federalist 39 states that" the last paper having concluded the observations which were meant to introduce a candid survey of the plan of government reported by the convention, we now proceed to the execution of that part of our undertaking."
Federalist 46 states that "The remaining points on which I propose to compare the federal and State governments, are the disposition and the faculty they may respectively possess, to resist and frustrate the measures of each other."

These suggest that united states grow as a republic and still handle factionalism because it still has arguments between small groups within the country.
