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.

What is the difference between a prime number and a prime factor?
Not a lot. They're both prime numbers. A factor that is prime is used to make other numbers.
Are prime factors and prime factorization the same?
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
