  Let $n \geq 1$ be a squarefree integer, and let $M$, $A$ be two groups of
order $n$. Using our previous results on the enumeration of Hopf-Galois
structures on Galois extensions of fields of squarefree degree, we determine
the number of skew braces (up to isomorphism) with multiplicative group $M$ and
additive group $A$. As an application, we enumerate skew braces whose order is
the product of three distinct primes.
