Students find the greatest common factor of two numbers. In this algebra activity, students use prime factorization to find their factor to simplify equations. they create a factor tree to find the factors of composite numbers.

Solving factor trees is a helpful way to introduce prime numbers. Your math class practices using this method along with two-column tables to find if a number is prime or not. They also learn other vocabulary, such as composite numbers,...

Seventh graders practice applying the rules of divisibility.

Students work with prime numbers. In this prime factorization lesson, students review writing numbers in their prime factorization form and solve multiple problems.
