%F a(n) = gcd(n,A366282(n)) = gcd(A366275(n),A366282(n)).

%F a(n) = n / A366284(n) = A366275(n) / A366285(n).

%o (PARI) A366283(n) = gcd(n,A366275(n)); \\ Uses the program given in A366275.

%Y Cf. A057889, A163511, A366275, A366282, A366284, A366285, A366286.

%Y Differs from related A364255 for the first time at n=25, where a(25) = 25, while A364255(25) = 5.
