Explanation: after finding the prime factorisation, add 1 to each exponent and multiply to obtain the new number, which is the number of divisors. This works because any divisor of 9600 can be expressed in the form 2 a ∗ 3 b ∗ 5 c.
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). For example: WebJul 17, 2015 · First of all, the last formula should be ( a 1 + 1) ( a 2 + 1) … ( a r + 1) (I suppose it was a typo).
