What is composite number and smallest composite number?
What is the Smallest Composite Number? A composite number has more than two factors, other than 1 and the number itself. Here, 4 satisfies this condition, and there is no other number smaller than 4 which is composite. Therefore, 4 is the smallest composite number.
What is a smallest composite number?
Smallest Composite Number 3 is not a composite number because it has only two divisors, i.e., 1 and the number 3 itself. However, when we come at number 4, we know that its divisors are 1, 2, and 4. Number 4 satisfies the criteria of a composite number. So, 4 is the smallest composite number.
