Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
or
List the factors.
1, 2, 3, 5, 6, 10, 15, 30
1, 2, 3, 6, 7, 14, 21, 42
Two methods to solve a greatest common factor (GCF) problem are the prime factorization method and the listing method. In the prime factorization method, you find the prime factors of each number and determine the common factors. The GCF is the product of the common prime factors. In the listing method, you list the factors of each number and find the common factors. The GCF is the greatest common factor from the common factors list.
there are seven steps in scientific methods to solve the problem 1.Systamatic observation 2.Controlled experment 3.Qualitative reasoning 4.Quantitative reasining 5.Mathamatical modeling 6.Predection 7.Verification
First tell me a problem and might understand
x= 1.5 4x -2=4 <<< Original problem +2 +2 <<< reverse operations (problem requires subtraction, so add to solve) 4x=6 <<< New problem 4x/4=6/4 <<<reverse operations (new problem requires multiplication, so divide to solve) x=1.5 <<< answer
35g^2h-15gh^2
The GCF is 2.
The easiest and most efficient is by prime factorization.Example: 30 and 42Factor them.2 x 3 x 5 = 302 x 3 x 7 = 42Select the common factors.2 x 3 = 6, the GCF
a strategy is a plan you have devised to solve a particular problem for yourself whereas a method is a set plan that everyone uses for the same problem eg 2+2=4
34 = 2x17 64 = 2x2x2x2x2x2 GCF = 2
1. interview the user and back up data 2. Estabish a theory 3. test your theory 4. plan the six and resolve the problem 5. Verify and prevent 6. Document the solve problem

Since 27 is a factor of 54, it is automatically the GCF of this problem.27. 27*2=54.Since 27 is a factor of 54, it is automatically the GCF of this problem.
This looks more like a factoring problem than a GCF problem. Since those three terms have nothing in common, the GCF is 1. But as an equation, it factors to (x + 5)(3x + 2)
