Will every factor pair in an array have an equal pair why or why not?

Yes, every factor pair in an array will have an equal pair, as factors are defined such that when multiplied together, they produce the original number. For example, if ( a ) and ( b ) are factors of a number ( n ), then ( a \times b = n ). In an array, each factor ( a ) will have a corresponding factor ( b ) such that both pairs are equal in their product, ensuring balance within the factor pairs. However, the arrangement of these pairs may differ depending on the context of the array.
