Monomial Greatest Common Factor
Sal explains that the greatest common factor of any number is the largest number divisible into both monomials and not necessarily the number with greatest value. He breaks down two numbers into their prime factors as a product of its primes then identifies the GCF of greatest common factor.
Greatest Common Divisor
In this greatest common divisor worksheet, students use prime factorization to determine the greatest common factors of two or more numbers. Explanations and examples are provided. This two-page worksheet contains ten problems.
More Factors and Multiples: Greatest Common Factor
ï»¿ï»¿In this greatest common factor worksheet, learners answer multiple choice questions about how to find the greatest common factor and actually finding it in problems. Students answer 10 questions total.
More Factors and Multiples: Greatest Common Factor: Pre Test
In this greatest common factor learning exercise, students answer multiple choice questions about problem solving and rules of the greatest common factor in numbers. Students complete 10 questions total.
Finding the Greatest Common Factor
In this math worksheet, students learn to find the greatest common factor and simplify fractions. Students read the information and follow the step by step directions to find the GCF in 10 problems.
Greatest Common Factor (GCF)
Students find the greatest common factor of two numbers. In this algebra lesson plan, students find the the prime and composite common factor of integers. This assignment is modified for special education students.
Factors and Multiples - Grade Six
Learners complete activities to practice identifying greatest common factors and least common multiples. They will use real-world problems to practice with. The lesson plan provides problems and a well-written outline to use when teaching these skills as well as a variety of worksheets that you can assign.
Paper Pool: Analyzing Numeric and Geometric Patterns
Students play a pool game to better explain ratio, proportion, greatest common divisor, and least common multiple.
Smart Cookie Factors
Learners examine the concept of finding the greatest common factor. They complete number of activities as they practice identifying prime and composite numbers. Pupils apply rules of divisibility and find the greatest common factor while completing worksheets.
Factoring Numbers: Greatest Common Factor
In this factoring numbers worksheet, students observe two numbers, list their factors, and designate the greatest common factor. Students solve 10 problems.
Factoring Numbers: Greatest Common Factor 2
In this factoring numbers instructional activity, students list the factors for pairs of numbers and determine the greatest common factor. Students solve 10 problems.
Greatest Common Factor
These multiples share a few factors, but which one is the greatest? Scholars list the factors for various number pairs, first just indicating common factors. Next, they do the same but write down the greatest common factor. Finally, there are two sets asking mathematicians to find the GCF between three numbers. There is an example to demonstrate the three-number problem. Instructions encourage kids to physically circle the common factors.
Fractions in lowest terms
Watch Sal simplify the fraction 48/64 to its lowest terms. He draws a candy bar to represent the whole and explains what the fraction 48/64 means. He groups each number by its greatest common divisor as a way to determine how he will divide. His process is thoroughly explained and would be appropriate for 5th or 6th grade students.
Reteaching Page 4.3 Finding the Greatest Common Factor
A bit of instruction on how to find the greatest common factor opens the worksheet. Leanrers are then given three practice pairs of numbers. Then the assignment goes on to describe prime factorization, and also provides three more practice pairs. This is an apt assignment for practicing factoring skills.
