Prime Factors In Java Explained Step-by-Step | Master In Looping in Java

In this tutorial, we will learn how to print all Prime Factors of a Number in Java using a clear and step-by-step explanation. This video is specially designed for ICSE Class 10, ISC Class 11 & 12 Computer Science students, as well as B.Tech, BCA, MCA, CS, IT, and IIT-level students who want to strengthen their understanding of prime numbers, factorization, and mathematical programming concepts and improve their logical programming skills.

A Prime Factor is a factor of a number that is also a prime number. Prime factorization is one of the most important concepts in mathematics and computer science because it is widely used in number theory, cryptography, algorithms, divisibility problems, and optimization techniques.

For example:

Prime factors of 84 are:
2, 2, 3, 7

Because:
84 = 2 × 2 × 3 × 7

In this video, you will learn how to find factors of a number, check whether a factor is prime, repeatedly divide the number by its prime factors, and print all prime factors step-by-step. The tutorial includes clear explanation of logic, complete Java program writing, manual dry run, and output verification, making it suitable for beginners as well as intermediate learners.

This topic is frequently asked in ICSE and ISC board exams, university practical exams, coding assignments, and technical interviews, making it an essential concept for Java learners.
