Which is the greatest common factor of 4?
In this case, the greatest common factor is 4. This calculator only accepts positive integers as input to calculate their common factors. While only two numbers are used in the above example, the calculator can compute the common factors of more than two numbers.
How to calculate the greatest common factor GCF?
Referring to the previous example, if instead the desired value were GCF (268442, 178296, 66888), after having found that GCF (268442, 178296) is 2, the next step would be to calculate GCF (66888, 2). In this particular case, it is clear that the GCF would also be 2, yielding the result of GCF (268442, 178296, 66888) = 2.
Which is the greatest common factor for 8, 12, 20?
Answer: GCF = 4. for the values 8, 12, 20. Solution by Factorization: The factors of 8 are: 1, 2, 4, 8. The factors of 12 are: 1, 2, 3, 4, 6, 12. The factors of 20 are: 1, 2, 4, 5, 10, 20. Then the greatest common factor is 4. You can also find the GCF using.
Which is the most common factor of 16?
The factors of 16 include: 1, 2, 4, 8, and 16. The factors of 12 include: 1, 2, 3, 4, 6, and 12. Thus, the common factors of 16 and 12 are: 1, 2, and 4. Often in math problems, it can be desirable to find the greatest common factor of some given numbers. In this case, the greatest common factor is 4.
