Diana:
Look up DivisorSigma. Table[DivisorSigma[1,x],{x,10,100}] will
give you what you want directly, I believe.
Best,

Subject: [mg39098] [mg39036] Repetitive sums of divisors
All,
I know that I can generate the divisors of any integer with the
"Divisors"
command. I would like to start with "x" = 10, for example, and generate
the divisors of "x", and then determine the sum of the divisors. I would
then like to increment "x", up to 100, for example.
Some help with this? Thanks,
Diana
