It is called a sieve.
Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.
One method for finding prime numbers is called the "Sieve of Eratosthenes" because it basically "sifts" through the numbers looking for numbers that are not not prime.
Eratosthenes
The method of sieving the multiples of prime numbers until only the prime numbers remain, while attributed to Eratosthenes, is originally thought to have been the work of Nicomachus.
Eratosthenes created a sieve that will do that.
Eratosthenes, It says it is Eratosthenes.
Prime numbers are not invented.
The sieve of Eratosthenes is a simple, ancient algorithm for finding all prime numbers up to any given limit.
Eratosthenes lived between 276 and 194 B.C. He didn't discover prime numbers; he devised a simple way to determine what numbers are prime in a given range.
The algorithm for identifying prime numbers which is known as the Sieve of Eratosthenes has been accepted as accurate for thousands of years.
prime numbers
The mathematical term "sieve of Eratosthenes" is defined as a simple algorithm for finding all prime numbers up to a given limit. It is named after a famous Greek mathematician of the same name.
