Finding GCF by using Prime Factorization

The Greatest Common Factor (GCF) of some numbers, is the largest number that divides evenly into all of the numbers. The prime factorization of a number involves breaking that number down to its smallest parts. This game will show you a way to discover the prime factors of a number (2-210) and after the Greatest Common Factor . A prime number is any number that is only divisible by itself and 1.The funny teacher asks three numbers from the student (2-210), in order to find the greatest common factor and through a procedure of continuing questions the student is called to find the smallest prime number, who can divide accurately the chosen number every time. Every right answer takes 1 point. According to how many prime numbers must multiply to create the chosen number, the student must answer some questions.We have to make the procedure of Prime Factorization for three numbers and the student must answer all relevant questions. After that, the student will know all prime factors of the three numbers and he must find the Greatest Common Factor. This is a helpful teaching resource for Teachers, Parents and Students.
