Prime numbers are whole numbers greater than 1 that are not divisible by any whole number other than 1 and itself. The first few are 2, 3, 5, 7, 11, 13 … To explain how the RSA algorithm works ...

Prime numbers can only be divided by themselves and 1. Figuring out which numbers are prime can be tricky, so mathematicians have developed various algorithms to speed up the search.

Fortunately, Édouard Lucas developed a prime number test in 1878, later proved by Derrick Henry Lehmer in 1930. Their work resulted in an efficient algorithm for evaluating potential Mersenne ...

Therefore, if an 'algorithm that enables prime factorization of a huge number of digits' is developed, its safety will be shaken.

The online computer game “Is this prime?” tests a player’s knowledge of prime numbers—and just surpassed 2,999,999 attempts. Give it a whirl.
