What is the smallest prime number ? Solution: A prime number is a number that has only two factors, that is 1 and the number itself. The smallest non-zero number is 1. The factor of 1 = 1 1 has only one factor which is 1 itself. The next smallest non-zero number is 2. Factors of 2 = 1 and 2 It has only two factors, 1 and the number itself 2. Therefore, 2 is the smallest prime number . Prime numbers are natural numbers greater than 1, having exactly two factors, 1 and the number itself. It can also be defined as a whole number that can’t be exactly divided by anything except 1 and itself. Thus negative numbers cannot be prime . They are important in mathematics because they are the building blocks of the natural numbers . 2, 3, 5, 7, 11, 13, 17, 19 are a few examples of prime numbers . A prime number is a natural number greater than 1 and has exactly two positive divisors: 1 and itself. Numbers that have more than two divisors are called composite numbers The smallest prime number is 2. Prime numbers are positive integers greater than 1 that have exactly two positive divisors, 1 and the number itself. In other words, a prime number is a number that is only divisible by 1 and itself. Examples of other prime numbers are 3, 5, 7, 11, and 13. Whereas, 4, 6, 8, and 9 are not prime because they have other divisors in addition to 1 and themselves. Prime numbers play an essential role in number theory and have many applications in cryptography and ...
