# Which Of The Following Is A Composite Number? 67,73, 89, 91?

A composite number refers to a positive integer that has a positive divisor other than one or itself. By definition, every integer that is greater than one is either a prime number or a composite number. In the above list of numbers there is only one composite number that is 91, which is divisible by 7. The rest of the numbers can either be divided by 1 or by themselves.

A composite number is defined by the fact that it has more than two factors, as apposed to a prime number, which has two factors, 1 and itself.  The first few primes are 2,3,5,7,11,13, etc.  91 is the only composite one, as it is divisible by 7 and 13.  Thus, it has four factors, 1,7,13, and 91, and is therefore not prime.
