  We prove that a Malcev algebra $\mathcal{M}$ containing the $7$-dimensional
simple non-Lie Malcev algebra $\mathbb{M}$ such that $m\mathbb{M}\neq 0$ for
any $m\neq 0$ from $\mathcal{M}$, is isomorphic to
$\mathbb{M}\otimes_\textup{F} \mathcal{U}$, where $\mathcal{U}$ is a certain
commutative associative algebra. Also, we prove that a Malcev superalgebra
$\mathcal{M}=\mathcal{M}_0\oplus \mathcal{M}_1$ whose even part $\mathcal{M}_0$
contains $\mathbb{M}$ with $m\mathbb{M}\neq 0$ for any homogeneous element
$0\neq m\in \mathcal{M}_0\cup \mathcal{M}_1$, is isomorphic to
$\mathbb{M}\otimes_\textup{F}U$, where $U$ is a certain supercommutative
associative superalgebra.
