Comments

A318366(n) computes a sum over the divisors of n in such a way that A318366(n) only depends on the prime signature of n. A025487 lists least numbers with a given prime signature with the exponents in nonincreasing order. This sequence hence shows this sum over divisors for distinct prime signatures.
