Web埃拉托斯特尼篩法(希臘語: κόσκινον Ἐρατοσθένους ,英語: sieve of Eratosthenes ),簡稱埃氏篩,也稱質數篩,是簡單且歷史悠久的篩法,用來找出一定範圍內所有質數。. 原理是從2開始,將每個質數的各倍數標記成合數。 一個質數的各個倍數,是一個差為此質數本身的等差數列。 WebConclusion. The simple sieve of eratosthenes is an algorithm that is used to find prime numbers in the range 1 to a given n. In the sieve of Eratosthenes algorithm, we maintain a boolean vector of numbers from 1 - n, and mark composite numbers as False. This is done by taking the smallest numbers starting from 2, and then marking it's multiples ...
