Answer:

Psychology is the scientific study of the mind and behavior, according to the American Psychological Association. Psychology is a multifaceted discipline and includes many sub-fields of study such areas as human development, sports, health, clinical, social behavior and cognitive processes.In number theory, two integers a and b are relatively prime, mutually prime, or coprime if the only positive integer that evenly divides both of them is 1. One says also a is prime to b or a is coprime with b. Consequently, any prime number that divides one of a or b does not divide the other.
