Uses of Prime and Composite Numbers in Real life Let us apply prime factorization for some composite and prime numbers. Prime factors are factors of a number that are prime numbers. Prime factorisation is a procedure to get the prime factors of a given number. Prime Factorisation of Composite and Prime Numbers It can be written as the product of two or more numbers It can only be written as a product of two numbers ( \(1\) and the number itself ) It is divisible by more than two numbers.
There are some differences between the prime numbers and the composite numbers. In the following chart, the boxes coloured in blue are the composite numbers.ĭifference Between Prime and Composite Numbers Here is the list of composite numbers from \(1\) to \(100\). There are many composite numbers in the number system. It means the HCF of two prime numbers is always \(1\).Ĭomposite Numbers List from \(1\) to \(100\) Chart Two prime numbers are always coprime to each other.All prime numbers are odd except \(2\) or we can say that \(2\) is the only even prime and the smallest prime number.A prime number can have only two factors.Some of the properties of prime numbers are:
A composite number can be formed by the product of two or more prime numbers.A composite number is divisible by a composite number as well as a prime number.We can get a composite number if we multiply two or more two positive integers other than \(1\).Composite numbers have more than two factors.Some properties of composite numbers are: Knowing some basic properties are essential to identify a prime number or a composite number.
