The Integers 801 to 900

• Count(d(N)) is the number of positive divisors of n, including 1 and n itself.
• σ(N) is the Divisor Function. It represents the sum of all the positive divisors of n, including 1 and n itself.
• s(N) is the Restricted Divisor Function. It represents the sum of the proper divisors of n, excluding n itself.
• For a Prime Number, Count(d(N))=2. The only divisors for a Prime Number are 1 and itself.
• A Deficient Number is greater than the sum of its proper divisors; that is, s(N)<n.
• An Abundant Number is less than the sum of its proper divisors; that is, s(N)>n.
• A Perfect Number equals the sum of its proper divisors; that is, s(N)=n.
