5 if a factor of itself. To answer the question pick any other number that has 5 as a factor. For example 25. The GCF or GCD of 5 and 25 is 5.
You can also use 5 and 125.
5 and 10, among many others.
Many numbers have a GCF of 5. Here are some examples:
5 and 10, 5 and 15, 10 and 25
35 and 75, 195 and 305
Most Common Factor, Greatest Common Factor, Highest Common Factor... all the same thing.
-- The common factors of 3, 15, and 9 are 1 and 3 . -- Their greatest common factor is 3 . -- When discussing numbers, there is no such thing as the 'most' common factor.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. When put in a list, the largest of these is known as the greatest common factor, or GCF. Some people refer to this as the highest common factor, or HCF. Calling it the most common factor would be confusing, since people tend to think of "most common" as something that happens frequently.
Example: 30 and 42The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The common factors are:1, 2, 3, 6The Greatest Common Factor:GCF = 6
You need at least two numbers to find something in common.
The greatest common factor is the highest number that can be divided equally into two or more numbers.
There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

The greatest common factor of any set of integers is infinite.
39 has a couple factors: 1, 3, 13, 39. Its greatest factor would be 39. HOWEVER, it doesn't have a common factor. You need two numbers to find what their greatest common factor is. For instance: 8 and 12. 8 has 1,2,4,8 and 12 has 1,2,3,4,6,12. The factors they have in common are 2 and 4, with 4 being their GCF. So 39 cannot have a common factor unless there is another number!
I guess the most common methods are the following: 1) List the common factors, and check which one is greatest. 2) Split each of the numbers into prime factors. Take all common factors and multiply them. 3) Euclid's algorithm. This method is fastest for large numbers.
The GCF is 4.
You Have To Do A Factor Tree Then Find What The Most Common Number In Both Of The Numbers. For Example. 24 40 / \ / \ [2] 12 4 10 / \ / \ / \ [2] 6 [2] [2] [5] / \ [2] [3] The GCF (Greatest Common Factor) is 2.
In math, a common factor usually refers to a factor that two or more numbers have in common. But, if you mean the most frequently occurring factor, that would be different. Since 1 divides every number, it would be the most common (frequently occurring) factor.
