WebAlgorithm. Sieve of Eratosthenes is a simple and ancient algorithm (over 2200 years old) used to find the prime numbers up to any given limit. It is one of the most efficient ways to find small prime numbers (<= $10^8$ ). For a given upper limit the algorithm works by iteratively marking the multiples of primes as composite, starting from 2. WebOdd Primes are numbers that can be expressed in the form 2n-1.

Web1 Answer. Sorted by: 1. One can check that a number smaller than 100 is a prime just by checking that it is not divisible by 2, 3, 5, 7. This is because the next prime after 7 is 11, whose square is greater than 100 (hence the test holds if one replaces 100 by 120, note also that checking the divisibility by 9 is useless since 3 divides 9).
