Divisor Count of 8128

Example of Use of Divisor Counting Function

 * $\map {\sigma_0} {8128} = 10$

where $\sigma_0$ denotes the divisor counting function.

Proof
From Divisor Counting Function from Prime Decomposition:
 * $\ds \map {\sigma_0} n = \prod_{j \mathop = 1}^r \paren {k_j + 1}$

where:
 * $r$ denotes the number of distinct prime factors in the prime decomposition of $n$
 * $k_j$ denotes the multiplicity of the $j$th prime in the prime decomposition of $n$.

We have that:
 * $8128 = 2^6 \times 127$

Thus:

The divisors of $496$ can be enumerated as:
 * $1, 2, 4, 8, 16, 32, 64, 127, 254, 508, 1016, 2032, 4064, 8128$
