👉 In mathematics, a "p公积" is an object that has properties similar to those of prime numbers but are not necessarily primes themselves. These objects can be defined by their own unique properties and relationships with other mathematical objects. For example, in number theory, a p-integer is an integer that is greater than 1 and whose prime factors (prime powers) are less than or equal to n, where n is the highest power of any prime factor appearing in its prime factorization.
