• In determining the GCF of 3 and 1, case I applies because 3 is evenly divisible by 1. The GCF of 3 and 1 is 1, and therefore the GCF of 7 and 3

is also 1.

(a) The gcf method returns the greatest common factor of

parameters a and b, as determined by case I and case II. Write

the gcf method below. You are encouraged to implement this method

recursively

/** Precondition: a and b are positive integers.

Returns the greatest common factor of a and b, as described in part (a).

*/

public static int gcfint a, int b)

I've added the complete code as a text attachment

Explanation:

This declares two variables as integer for input

       int f1, f2;

Prompts the user for two positive integer inputs

       System.out.print("Enter two positive integers: ");

This gets the two integer input from the user

       f1 = input.nextInt(); f2 = input.nextInt();

If both inputs are positive, the function is called and the gcf is printed

       if (f1 >0&& f2 > 0){

       System.out.printf("G.C.F of %d and %d is %d", f1, f2, gcf(f1, f2));}

If otherwise, a message is printed stating that only positive input is required

       else{            System.out.print("Positive inputs only");        }

   }

The function begins here

gcf(int a, int b) {

If the second number (b) is 0, the function returns the first number (a)

       if () { return }

If otherwise, the function is called recursively

       else { (gcf(, )); }

   }

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.

cyberstalking on the internet means to harass or stalk someone, a group, or an organization. this may include defamation, slander, and false accusations. in many jurisdictions, cyberstalking is a criminal offense. 

on the other hand, cyberbullying focuses more on intimidating, threatening or harassing someone. harmful bullying include posting threats, rumors, and sexual remarks.
