With reference to this question, I am trying to generalize my previous question here.



If I have two GCD equations with common variable $m$ as follow: $GCD(m,p_i)=1$ and $GCD(m+7,p_i)=1$ where $p_i$ takes values from the first 20 prime numbers. can the two GCD equations be combined (since they both share second argument $p_i$)?



My target is to get all potential values of $m$ (in a given range, say from 1 to 1000). I thought if we can combine the two GCD equations into one GCD equation (for each $p_i$) then we have probably good base to calculate all values of m.

  • $gcd(m,p_i)=1$ and $gcd(m+7,p_i)=1$ combine to give $gcd(m(m+7),p_i)=1$.
