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 Erastosthenes shows prime numbers.
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.
Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.
It is a simple Algorithm to find prime numbers up to a given number 'N' discovered by an Indian Student Mathematician S.P. Sundaram. More details can be found at http://en.wikipedia.org/wiki/Sieve_of_Sundaram
The Sieve did not invent prime numbers. It was used to find them.
The Sieve of Erastosthenes shows prime numbers.
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.

The sieve of Eratosthenes is a simple, ancient algorithm for finding all prime numbers up to any given limit.
