Notice that this list of prime numbers contains only odd numbers, apart from 2. What is the smallest prime number? 2 is the smallest prime number. It also the only even prime number – all other even numbers can be divided by themselves, 1 and 2 at least, meaning they will have at least 3 factors.The correct option is B 2 1 is neither a prime number nor a composite number. It is a unique number with only one factor. Factors of 2 = 1, 2 So, 2 is the smallest prime number. Factors of 4 = 1, 2, and 4 Factors of 6 = 1, 2, 3, and 6 These have more than two factors and are composite numbers.
A number is a divisor of another number when the remainder of Euclid’s division of the second one by the first one is zero. Concerning the number 2, the only two divisors are 1 and 2. Therefore 2 is a prime number. The number 2 features several interesting properties: 2 is the smallest prime number; 2 is the only even prime number
Therefore, $ 2 $ is the smallest prime number. So, the correct answer is “Option B”. Note: A prime number will have only two factors, 1 and number itself, whereas a composite number has more than two factors. All even numbers except 2 are composite. All prime numbers except 2 are odd. 1 is neither a prime number nor a composite .
It is best to start working from the smallest prime number, which is 2, so let's check: 12 ÷ 2 = 6. Yes, it divided exactly by 2. We have taken the first step! But 6 is not a prime number, so we need to go further. Let's try 2 again: 6 ÷ 2 = 3. Yes, that worked also. And 3 is a prime number, so we have the answer: 12 = 2 × 2 × 3
The smallest prime number is 2, which is the only even prime number. 3 is the smallest odd prime number. Largest Prime Number: There exists no largest prime number as the natural numbers do not end.

[2] Relatedly, it is the third Carmichael number, [3] and specifically the first Chernick–Carmichael number. [a] Furthermore, it is the first in the family of absolute Euler pseudoprimes, a subset of .
The numbers 3 11 and 5 13 are odd numbers as any product of odd numbers is odd and it is known that the sum of two odd numbers is an even number. An even number is divisible by 2 and 2 is a prime number.

Interestingly, 2 is also the only even number which is a prime number. What are the Even Prime Numbers from 1 to 100? 2 is the only even prime number from 1 to . The classical Sieve of Eratosthenes algorithm takes O(N log (log N)) time to find all prime numbers less than N. In this article, a modified Sieve is discussed that works in O(N) time.Example : Given a number N, print all prime numbers smaller than N Input : int N = 15 Output : 2 3 5 7 11 13 Input : int N = 20 Output : 2 3 5 7 11 13 17 19 Manipulat Examples of prime numbers are \(2\) (this is the only even prime number), \(3, 5, 7, 9, 11, 13, 17, \ldots\). . = 2^4 \times 3^8\) (the lowest powers of all prime factors that appear in both factorizations) and \(lcm( 2^6 \times 3^9, 2^4 \times 3^8 \times 5^2)= 2^6 \times 3^9 \times 5^2\) (the largest powers of each prime factors that appear .
Given a number n, print least prime factors of all numbers from 1 to n. The least prime factor of an integer n is the smallest prime number that divides the number. The least prime factor of all even numbers is 2. A prime number is its own least prime factor (as well as its own greatest prime factor). Note: We need to print 1 for 1. Example :
