Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.
The word "sieve" in this context is used figuratively with reference to the fact that a sieve does not hold all its contents. Think of sprinkling numbers at the top of the page. The composite numbers get caught, the prime numbers sift on down.
prime numbers are invented by srinivasan ramanujan, an Indian mathematician.
To find prime numbers less than 100, the sieve of eratosthenes filters out 1 and all multiples of 2, 3, 5, and 7. All remaining numbers less than 100 are primes.
The sieve of Sundaram sieves out the composite numbers just as sieve of Eratosthenes does, but even numbers are not considered; the work of "crossing out" the multiples of 2 is done by the final double-and-increment step.
The sieve of Eratosthenes was discovered in 223 BC.
The Sieve of Eratosthenes filters numbers, letting the composites fall through while the primes remain.
Eratosthenes, a greek philosopher, did, hence the name.
About 276 BC Eratosthenes was a Greek mathematician who is credited with a simple method of making a list of as many primes as you wish. His method is known as the Sieve of Eratosthenes.
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.
Eratosthenes
The Sieve did not invent prime numbers. It was used to find them.
