Professor Hijibiji has defined the following Boolean algebra $\mathcal{B} = (B, +, *)$, where $B = \{1, 2, 3, 5, 6, 10, 15, 30\}$, i.e., the set of all eight factors of $30$; the two binary operators $’+’$ and $’*’$ respectively denote the LCM (least common multiple) and GCD (greatest common divisor) of two integer operands. Which are the identity elements for $\mathcal{B}$?
