1 votes 1 votes $m$ is said to be primitive root of $n$ if we are able to get all remainder from $0$ to $n-1$ when $m^k$ ($k = 1 \dots n-1$) is divided by $n$. Is it correct ?? Is $n$ necessarily has to be a prime number or it holds always true? thor asked Nov 29, 2016 thor 184 views answer comment Share Follow See all 0 reply Please log in or register to add a comment.
