Among, [sic] his other achievements, Matiyasevich and his colleague Boris Stechkin also developed an interesting “visual sieve” for prime numbers, which effectively “crosses out” all the composite numbers, leaving only the primes.
Given a list of consecutive numbers starting at 1, the Sieve of Eratosthenes algorithm will find all of the prime numbers.
