Divisor Count of 464

Example of Use of $\tau$ Function

 * $\map \tau {464} = 10$

where $\tau$ denotes the $\tau$ Function.

Proof
From Tau Function from Prime Decomposition:
 * $\displaystyle \map \tau n = \prod_{j \mathop = 1}^r \paren {k_j + 1}$

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:
 * $464 = 2^4 \times 29$

Thus:

The divisors of $464$ can be enumerated as:
 * $1, 2, 4, 8, 16, 29, 58, 116, 232, 464$
