Divisor Count of 40,314

Example of Use of Divisor Counting Function

 * $\map {\sigma_0} {40 \, 314} = 8$

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:
 * $40 \, 314 = 2 \times 3 \times 6719$

Thus:

The divisors of $40 \, 314$ can be enumerated as:
 * $1, 2, 3, 6, 6719, 13 \, 438, 20 \, 157, 40 \, 314$
