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 23 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 23 is 23
The greatest common factor of 22 and 23 is 1
Factors of 22: 1, 2, 11, 22
Factors of 4: 1, 2, 4
GCF (22, 4) = 2
1 is the gcf
The GCF is 1.
11 is the best one
The greatest common factor of 46 and 69 is 23.
The Greatest Common Factor of 23, 12, 8 is 1.
The greatest common factor of 23 and 100 is 1.
The greatest common factor of 14 and 23 is 1.
Both 23 and 29 are prime; their only factors are 1 and themselves. Therefore, the greatest common factor is 1.
The greatest common factor of 3 and 23 is 1
The Greatest Common Factor of 9, 23 is 1.
The greatest common factor of 46 and 69 is 23.
The greatest common factor of 23 and 100 is 1.
The greatest common factor of 14 and 23 is 1.
The Greatest Common Factor of 23, 43, 35: 1
The GCF is 1.
greatest common factor of 161 and 46 is 23.
The Greatest Common Factor of 23, 12, 8 is 1.
The greatest common factor of 8 and 23 is 1.
Short answer: There are none.There is neither a greatest common factor nor common factors of a single number, such as 23, 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.Examples:The common factors of 23 and 25 are only 1; the greatest common factor is 1.The common factors of 23 and 69 are 1 and 23; the greatest common factor is 23.The common factors of 23 and 75 are only 1; the greatest common factor is 1.The factors of 23 are 1 and 23. For them to be common, they need to be compared to another set of factors.
Both 23 and 29 are prime; their only factors are 1 and themselves. Therefore, the greatest common factor is 1.
