Prime factors in java
Factors are the numbers we multiply to get another number.
factors of 14 are 2 and 7, because 2 × 7 = 14.
Some numbers can be factored in more than one way.
16 can be factored as 1 × 16, 2 × 8, or 4 × 4.
A number that can only be factored as 1 times itself is called a prime number.
The first few primes are 2, 3, 5, 7, 11, and 13.
The list of all the prime-number factors of a given number is the prime factors of a number. The factorization of a number into its prime factors and expression of the number as a product of its prime factors is known as the prime factorization of that number. The prime factorization of a number includes ONLY the prime factors, not any products of those prime factors.
Program
import java.util.Scanner; public class PrimeFactors { public static void main(String args[]){ int number; Scanner sc = new Scanner(System.in); System.out.println("Enter a number ::"); number = sc.nextInt(); for(int i = 2; i< number; i++) { while(number%i == 0) { System.out.println(i+" "); number = number/i; } } if(number >2) { System.out.println(number); } } }
Output
Enter a number 24 2 2 2 3
