Let's try one.
30x2y3z4 + 42x4y5z2
Do the numbers first.
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6
For the variables, select the lowest exponent.
The GCF of the above expression is 6x2y3z2
Yes. The GCF of 2x2 and 4x3 is 2x2
Yes.
The GCF is 3. No exponents needed.
The common factors are 1 and 3. The greatest of these is 3.
The common factors are: 1, 2, 4, 8, 16The Greatest Common Factor = 16
The common factors are 1 and 7. The GCF is 7.
The two common factors are: 1, 7
The GCF is 3. No exponents needed.
The greatest common factor is the largest of the common factors.
The common factors are 1 and 3. The greatest of these is 3.
The common factors are: 1, 5 The Greatest Common Factor (GCF) is: 5
What are the greatest common factors of 990 and 1540
1,2,5,10 are the common factors, and the Greatest Common Factor is 10.
The common factors are: 1, 2 The Greatest Common Factor: 2
the greatest common factors of what? The question makes no sense as it stands.
The common factors are: 1, 2, 4, 8, 16The Greatest Common Factor = 16
The common factors are 1 and 7. The GCF is 7.
The two common factors are: 1, 7
The common factors are: 1, 3 The Greatest Common Factor (GCF) is: 3
