## Welcome to the Page of Factoring, Primes GCF and LCM

Here Teachers,Parents and Students can find a collection of games and activities in order to help student to improve understanding in math skills such as the following:

• Prime and composite numbers
• Prime Factorisation
• Highest Common Factor
• Lowest Common Multiple
• Identify Factors

#### Prime Factorisation Game

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 factorization of any number

#### Finding LCM by using Prime Factors

In this game, the funny teacher selects random three numbers 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.After, the student will know all prime factors of the three numbers and he must find the Least Common Multiple e.g LCM of 12 and 30 12=2*2*3 and 30=2*3*5 LCM=2^2*3*5=60 Using the set of prime numbers from each set with the highest exponent value

#### Finding GCD by using Prime Factors

In this game, the student selects three numbers (0-210) 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.After, the student will know all prime factors of the three numbers and he must find the Greatest Common Divisor e.g GCD OF 30 and 12 30=2*3*5 and 12=2*2*3 and GCD=2*3 the product of common factors
