How to find Largest Prime Factor of a Number in Java - Programming Kata One of the common programming kata to learn coding is write a program to find the largest prime factor of a number.

Like any other programming problem, you need to build the logic to solve this problem. Prime factors of a positive integer are the prime numbers that divide the number exactly i.

A positive integer can have multiple prime factors, our challenge is to find the largest prime factor of a number. In one of earlier problemwe have learned how to find prime factor of a number in Java and we will use the similar logic here, but instead of returning a list of prime factors we will only return the largest prime factor.

Write a program to find the largest prime factor of a positive integer in Java. If we pass 15 to your program, it should return 5, and if we pass 6 to your program it should return 3. As we learned a number is called prime factor if it is prime number and it can divide the number exactly.

Another property of prime factor is that if we keep dividing the number by prime factor then it will either fully divide the number or produce another prime factor e.

On other hand if need to find prime factor of 15, then we first try to divide it by 2, but since its not divisible by 2, we move to next number which is 3. Since 3 can divide 15, it produces another prime number 5, now 5 is not divisible by anything other than 5, so 3 and 5 become prime factor of In our program, we have used the same logic.

We start with 2, the smallest prime number and try to divide the number, if number is divisible then we keep dividing it by same number until its not divisible any more. Now we move to next number, the largest number which is able to fully divide the input is our largest prime factor.

This would be more clear when you see the actual program. Here is our unit test to check couple of more numbers: One thing to note here is that we are not handling invalid input here e. You can throw IllegalArgumentException for those inputs which are not valid as per problem specification.

Similarly, you also need to include unit test to check those invalid inputs.

I leave that task for you as practice. This is a really good exercise to learn coding when you are starting with Java or Python or any other programming language.

This kind of problem will help to build your programming logic and improve your coding skill. Believe me, its not easy to convert a real life algorithm into program without practice. You must solve some basic coding problem based upon String, array and recursion to get hold of coding.

I have shared many such exercise in this blog, if you are interested you can also take a look at following list of problem: Trick Write a program to check if LinkedList contains loop in Java?

C++ Program to Display Factors of a Number. Example to find all factors of an integer (entered by the user) using for loop and if statement.

If n is perfectly divisible by i then, i will be the factor of n. In each iteration, the value of i is updated (increased by 1). This C++ Program which displays the factors of the given number. The program takes number from the input and runs a while loop until the temporary variable reaches the given number.

C++ Program to Display Factors of a Number Example to find all factors of an integer (entered by the user) using for loop and if statement.

To understand this example, you should have the knowledge of following C++ programming topics. list of programs: Write a c program Find factors of number using for loop, Write a C program find factors of number using while loop, Write a C Program to find factors of numbers below n, Write a C Program to find factors of numbers between given range.

This C++ Program which displays the factors of the given number. The program takes number from the input and runs a while loop until the temporary variable reaches the given number.
