| Oct 10, 2019 at 9:46 | comment | added | Đào Thanh Oai | I mean $\frac{\varphi(A)}{A} \le \prod_{i=1}^n (1-\frac{1}{a_i})$ Where $\varphi(A)$ is the Euler's totient function | |

| Oct 10, 2019 at 9:39 | comment | added | Đào Thanh Oai | I belive the Euler's totient function is minimum: en.wikipedia.org/wiki/Euler%27s_totient_function | |
