Question

# Which of the following is the Smallest Prime Number?

• 1.1
• 2.2
• 3.4
• 4.6
Option 2:2
Solution

2 is the smallest prime number. The number one is neither a prime nor a composite number. With just one element, it is a singular number.

Factors of 2 = 1, 2

Therefore, 2 is the smallest prime number.

• Factors of 4 = 1, 2, and 4
• Factors of 6 = 1, 2, 3, and 6

These are composite numbers with more than two elements.

## Prime Numbers

A positive integer with exactly two elements, namely 1 and the number itself, is referred to as a prime number. A different definition of it is an integer or positive number that is not the sum of any other two positive integers save 1 and the number itself. If p is a prime, then 1 and p by itself are required to be its only factors. A composite number is any number that does not fall into this category and may be factored into other positive integers.

## Properties of Prime Numbers

The following is a list of some prime number characteristics:

• Every number greater than 1 has at least one prime number that it can be divided by.
• The sum of two prime numbers can be used to represent any even positive integer bigger than 2.
• All prime numbers other than 2 are odd. In other words, the only even prime number is 2, which is what we can assert.
• Coprime relationships between two prime numbers are constant.
• The prime factors that can be found for each composite number are all distinct in their own right.

Summary:

## Which of the following is the Smallest Prime Number?

2 is the smallest prime number. A prime number is a positive integer that has exactly two components, 1 and the number itself. Every number which is greater than 1 and has at least one prime number by which it can be divided.
