Divsum

Function: divsum (<n>, <k>)

divsum(5^2*7*13*19*41*43*47*51)/(2*5^2*7*13*19*41*43*47*51), numer;

Function: divsum (<n>) divsum (<n>, <k>) returns the sum of the divisors of <n> raised to the <k>th power.

divsum (<n>) returns the sum of the divisors of <n>.

          (%i1) divsum (12);
          (%o1)                          28
          (%i2) 1 + 2 + 3 + 4 + 6 + 12;
          (%o2)                          28
          (%i3) divsum (12, 2);
          (%o3)                          210
          (%i4) 1^2 + 2^2 + 3^2 + 4^2 + 6^2 + 12^2;
          (%o4)                          210

(%o1)                                true
(%i2)
