Kind of similar approach as the one suggested in question itself, but I think finding successive prime numbers is a problem in itself:
1. Create hashmap with key as String and value as list of strings.
2. For every word in file, sort the word and store the sorted word as key and append the actual word in the list of strings as value of hashmap.
3. After completing the scan of file, each entry in hashmap has the list of anagrams.

Just Instead of hashmap you can use trie data structure (all other parts remain the same) and this way you can avoid collisions and achieve same complexity

A trie Data structure will be more efficient. for this purpose.
Compare values with char sorting of words
node structure can be
Class TrieNode
{
public Dicitionary <Char,TrieNode> _Dictionary;
public list<int> _Index; //index of the word in the file
}
