One method for finding prime numbers is called the "Sieve of Eratosthenes" because it basically "sifts" through the numbers looking for numbers that are not not prime.
Yes
It is a number grid that only contains prime numbers.
I am assuming you are referring to a normal 3x3 sudoku grid, where you can only use the numbers 1-9 once in the grid, and by prime number you mean the 3digit number across and down the grid must be prime? For a number to be prime, it must end in 1, 3, 7 or 9. There are 5 places on the Sudoku grid for a number to finish and as you can only use a number once in sudoku you have one place left where the number can not be prime. This means the most you can have is 5 prime numbers.
Numbers with more than two factors are not prime numbers
X-axis and the second number is called The y-axis
Yes
Both a grid and a sieve is composed of vertical and horizontal lines with spaces in between. An example of a grid is a spreadsheet. An example of a sieve is a colander, or a gardener's riddle that is used to remove stones from soil.

One; the only even prime number is two.
it looks like a 100 square grid with 1 to 100 and you highlight all the prime numbers
