For the relation "is a proper factor of" defined on the set (2, 4, 8, 13, 16), express the relation as a set of ordered pairs.

Let (x,y) be the ordered pair where relation is defined as " x is a proper factor of y" Given set = {2,4,8,13,16} Then relation set containing ordered pairs is {(2,2), (4,2), (8,2),(16,2),(4,4),(8,4),(16,4),(8,8),(16,8), (16,16)}
