Numbers such that Divisor Count divides Phi divides Divisor Sum/Examples/630

Examples of Numbers such that Tau divides Phi divides Sigma
The number $630$ has the property that:
 * $\tau \left({630}\right) \mathrel \backslash \phi \left({630}\right) \mathrel \backslash \sigma \left({630}\right)$

where:
 * $\backslash$ denotes divisibility
 * $\tau$ denotes the $\tau$ (tau) function
 * $\phi$ denotes the Euler $\phi$ (phi) function
 * $\sigma$ denotes the $\sigma$ (sigma) function.
