"WebDivisors# How do you compute the sum of the divisors of an integer in Sage? Sage uses divisors(n) for the list of divisors of \(n\) , number_of_divisors(n) for the number of divisors of \(n\) and sigma(n,k) for the sum of the \(k\) -th powers of the divisors of \(n\) (so number_of_divisors(n) and sigma(n,0) are the same).
