Prime & Composite Numbers
Prime Numbers: Numbers which have only two factors are called the prime numbers. These two factors have to be number itself and the number one. For example; 2, 3, 5, 7, 13, 17, 19, 23 and 29 are all prime numbers. Can find more prime numbers below 100?
2 is only even number which is prime. 1 is not a prime number as it has only one factor which is itself.
Composite Numbers: Numbers which have more than two factors are called the composite numbers. Obviously numbers which are not prime numbers are composite numbers.
For example; 4, 6, 8, 9, 10, 12, 14, 15 etc. are all composite numbers. Can you find more composite numbers?
Don’t get confused with even and odd; prime and composite. Even numbers are divisible by 2 and odd numbers are not divisible by 2.
