Abstract: Following C. A. Spiro, who has found eight primes for which

$\displaystyle \operatorname{lcm}{({p_j} - {p_i})_{1 \leq i < j \leq 8}} = 5040,$

we show that for every set of eight odd primes $ \{ {q_1}, \ldots ,{q_8}\} $, one has $ 5040\vert\operatorname{lcm}({q_j} - {q_i})$. Moreover, $ \operatorname{lcm}({q_j} - {q_i}) = 5040$ infinitely often, under the assumption of the 8-tuple conjecture.
