Divisor Count of 748

Example of Use of $\tau$ Function

 * $\tau \left({748}\right) = 12$

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

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

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:
 * $748 = 2^2 \times 11 \times 17$

Thus:

The divisors of $748$ can be enumerated as:
 * $1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748$
