The number closest to the rectangle on an E-R diagram represents the maximum cardinality, which is the maximum number of relationships that an entity can have with other entities. For instance, if you have an entity called "students" and another entity called "courses," the maximum cardinality for the "students" entity could be represented by the number "10" next to the rectangle, indicating that a student could take up to 10 courses.
