DEFINITION
Given a positive integer n, let denote the number of positive divisor of n and denote the sum of this divisors.

• - The number of positive divisor of n
• - The sum of the positive divisor of n

Example:

1. n=6
   The divisions of 6 are 1,2,3,6
   So, T (n) = 4, σ (n) = 12
2. n=12
   The divisions of 12 are 1,2,3,4,6,12
   So, T (n) = 6, σ (n) = 28
3. n=100
   the divisions of 100 are 1,2,4,5,10,20,25,50,100
   So, T (n) = 9, σ (n) = 217
