No, you should continue checking for factor pairs even if you find a pair that repeats. A repeating pair indicates that the number is not a prime number, but there may be other factor pairs that have not been identified yet. It is important to exhaust all possible factor pairs to ensure that all factors of the number are identified accurately.
12 has three factor pairs, six if you count their negative counterparts.
