Yes, there are algorithms for prime factorization. Trial division, Fermat's factorization method, and the general number field sieve (GNFS) are common approaches. Trial division is simple but not efficient for large numbers. GNFS is the most efficient for very large integers. These algorithms are crucial for cryptography and number theory applications.
