Webb14 juli 2024 · 9, 15, 21 are examples of composite odd numbers. Smallest Composite Numbers. 1 is not a composite number because it has only one divisor 1. 2 and 3 have only two factors one and itself. In the case of 4, there are more than two factors. The factors of 4 are 1, 2, 4. So, the smallest composite number is 4. The smallest prime number is 2. WebbSuch numbers are called Composite numbers. Note: (i) 1 is neither a prime nor a composite number. (ii) 2 is the smallest prime number. (iii) 2 is the only even prime number. (iv) No prime number ends with zero or 5. A prime number is a natural number which has only two different factors, 1 and the number itself.
