Note that m can’t be prime itself. So there is some integer d such that d divides m and 1 < d < m. But now, e Dm=d is also an integer such that e divides m and 1 < e < m. By the minimality of m in C, we know d and e are both products of primes. henry tong md miWebTrình bày sàng Eratosthenes và cải tiến sàng Eratosthenes. Một số bài tập áp dụng và hướng dẫn giải.
