Yes, 3 is a prime number.
A prime number is defined as a natural number greater than 1 that has exactly two distinct positive divisors: 1 and itself. The number 3 meets this definition because it is greater than 1 and cannot be divided evenly by any positive integers other than 1 and 3. Consequently, it is not a composite number.
Answer details
Divisors of 3
A prime number must have exactly two distinct divisors. The only positive divisors of 3 are 1 and 3.
Not a composite number
Composite numbers must have more than two divisors. Since 3 only has two, it is classified as prime rather than composite.
Mathematical definition
Prime numbers are natural numbers greater than 1 that cannot be formed by multiplying two smaller natural numbers. 3 satisfies this condition.

Prime number
A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of
