Every row sum equals $15$, so $15$ is an eigenvalue.

Nope

This is not actual procedure

What do you mean by a actual procedure?

 If you try to expand $det(A-\lambda I )$ then we see  this matrix has four complex eigenvalues (but this is so long)

My answers shows $Ax=15x$ with $x=(1,1,1...,1)^T$

Are  you know this fact? : In a square matrix A with every row sum equals k, then k is an eigenvalue of A
