The number 85 is a composite number. To understand really, we need to know what are prime and composite numbers. A prime number is a natural number that has no other divisor only 1 and the number itself. On the other hand, composite number is a number that can be divided evenly by numbers other than 1 and itself and this is where 85 falls. 85 can divided evenly by 5 and 17.
