One of the most common and the best way of cracking RSA encryption is to begin to derive the two prime numbers, which are used in the RSA PKI mathematical process. If the two numbers p and q are discovered through a _____________ process, then the private key can be derived.

Explanation:
In April 1994, an international cooperative group of mathematicians and computer scientists solved a 17-year-old challenge problem, the factoring of a 129-digit number, called RSA-129, into two primes. That is, RSA-129 = 1143816257578888676692357799761466120102182 9672124236256256184293570693524573389783059
