Question

write a java program to print the factors of a number and also the product​

Answer 1

Answer:

The following Java program prints the factors of a number and also the product:

public class Factors{

public static void main(String[] args)

{

int num=10;

int i;

int prod = 1;

for(i=1;i<=10:i++)

{

if(num%i==0)

     System.out.print(i);

     prod = prod * i;

}

System.out.printn(prod):

}

}

Explanation:

The factor of a number:

A factor of a number is defined as that number that can divide the number completely.

For example: 10 can be completely divided by 1, 2, and 5. So 1, 2, and 5 are the factors of 10.

Now let's understand the program that we have written for finding the factors of a number:

• First, we create a public class named Factors and inside that class, we define our main function.
• Then we write our number in the num variable.
• A for loop is used that will run from 1 to the number and every time we check whether the value of i can divide the number or not.
• If i can divide a number completely it means that i is a factor of the number, otherwise not.
• Product is calculated for every factor.
• Lastly, we print the output.

Answer 2

Answer:

java program to print the factors of a number

public class Main {

 public static void main(String[] args) {

   // positive number

   int number = 60;

   System. out.print("Factors of " + number + " are: ");

   // loop runs from 1 to 60

   for (int i = 1; i <= number; ++i) {

     // if the number is divided by i

     // i is the factor

     if (number % i == 0) {

       System.out.print(i + " ");

     }

   }

 }

}

OUTPUT:

Factors of 60 are : 1 2 3 4 5 6 10 12 15 20 30 60

• In the above program, a number whose elements are to be discovered is saved withinside the variable number (60).
• The for loop is iterated until i &lt;= number is false. In every iteration, whether or not the range is precisely divisible with the aid of using i is checked (the situation for i to be the aspect of number) and the value of i is incremented with the aid of using 1
