Avoiding DIVIS in Number Theory |
| Description: | Because the built-in DIVIS command can be slow, this has six commands useful in number theory that avoid using it: τ (how many divisors does X have?), σ (the sum of ALL the divisors of X), σ0 (the sum of the PROPER divisors of X), Ad (algebraic mean of the divisors of X), Hd (harmonic mean of the divisors of X), and Πd (product of all the divisors of X). |
