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.
Which of the following is the smallest prime number? (a) 1 (b) 2(c) 4 (d) 6
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.
