Examples

• The algorithm's primary function is to determine the primality of large integers.
• Mathematicians have studied the primality of numbers for centuries.
• A simple test for primality is to check for divisibility by all smaller prime numbers.

Advanced Usage

• Primality testing: Refers to algorithms and processes used to determine whether a given number is prime.
  • The development of efficient primality testing is crucial for cryptography.
• Primality certificate: A piece of information that can be used to verify the primality of a number.
  • The software provided a primality certificate for the newly discovered Mersenne prime.

Variants and Related Words

• Prime (adjective/noun): The core related term. As an adjective, it describes a number having the property of primality (e.g., a number). As a noun, it refers to the number itself (e.g., 7 is a ).
