## What are the prime number from 1 to 100?

If you just need a way to generate very big prime numbers and don't care to generate all prime numbers < an integer n, you can use Lucas-Lehmer test to verify Mersenne prime numbers. A Mersenne prime number is in the form of 2^p -1. I think that Lucas-Lehmer test is the fastest algorithm discovered for Mersenne prime numbers.

## What are the prime number from 1 to 100?

List of prime numbers to 100. 2, **3, 5, 7, 11, 13, 17, 19, 23, 29, 31**, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

## Which is the fastest algorithm to find prime numbers?

**Prime sieves**

**A prime sieve or prime number sieve** is a fast type of algorithm for finding primes. There are many prime sieves. The simple sieve of Eratosthenes (250s BCE), the sieve of Sundaram (1934), the still faster but more complicated sieve of Atkin, and various wheel sieves are most common.

## Which is the fastest prime factorization algorithm to date?

**Pollard's Rho** is a prime factorization algorithm, particularly fast for a large composite number with small prime factors. The Rho algorithm's most remarkable success was the factorization of eighth Fermat number: 1238926361552897 * 93461639715357977769163558199606896584051237541638188580280321.Apr 6, 2021

## Is there an algorithm to calculate prime numbers?

In mathematics, **the sieve of Eratosthenes** is an ancient algorithm for finding all prime numbers up to any given limit. ... One of a number of prime number sieves, it is one of the most efficient ways to find all of the smaller primes. It may be used to find primes in arithmetic progressions.
