If and are parallel in space then it have any number of vectors that are perpendicular to the both vectors.

Parallel vector : Vectors are parallel if they have the same direction.

Perpendicular vector : Vectors are perpendicular if they are in opposite direction.

Using the above statements of Parallel vector and Perpendicular vector we can justify that

if and are parallel in space, then it have any number of vectors that are perpendicular to the both vectors.
