FORMULA

a(n) = lcm(n, A276086(n)).

a(n) = A324580(n) / A324198(n).

PROG

(PARI)

A276086(n) = { my(m=1, p=2); while(n, m *= (p^(n%p)); n = n\p; p = nextprime(1+p)); (m); };

A328584(n) = lcm(n, A276086(n));

(PARI)

A006530(n) = if(n>1, vecmax(factor(n)[, 1]), 1); \\ From A006530.

A328584(n) = if(!n, n, my(m=1, p=2, orgn=n, maxp = A006530(n)); while(n || (p<=maxp), m *= (p^max(n%p, valuation(orgn, p))); n = n\p; p = nextprime(1+p)); (m));
