What is the smallest composite number?
- 4:Composite numbers are numbers that have more than two factors. Now, as we start counting: 1, 2, 3, 4, 5, 6, …. so on, we see that 1 is not a composite number because its only divisor is 1. 2 is not a composite number because it has only two divisors, i.e., 1 and the number 2 itself. 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.
