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 205 and 38 is 1.
There is neither a greatest common factor nor common factors of a single number, such as 820 because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 820 are 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, and 820. The prime factors of 820 are 2, 2, 5, and 41. Examples: The common factors of 16 and 820 are 1, 2, and 4; the greatest common factor is 4. The common factor of 21 and 820 is 1; the greatest common factor is 1. The common factors of 615 and 820 are 1, 5, 41, and 205; the greatest common factor is 205.
The GCF of 10 and 205 is 5.

The GCF is 5.
The GCF is 1.
The GCF is 5.
The gratest common factor known as gcf is five,5
A single number cannot have a greatest common factor because "common" refers to factors that two or more numbers have in common. You have only one number.
200-1,2,4,5,10,20,40,50,100,200 205-1,5,41,205 the answer is 5. it is the highest number that they have in common. (greatest common factor)
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.Since 82 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 82 is 82.It is only useful find the GCF of two or more numbers, like 82 and 41. The GCF of those two is 41. The GCF of 82 is obviously 82.
The common factors of 200 and 205 are: 1 and 5
