It is called a common factor!

A single number cannot have a greatest common factor. A greatest common factor is used to compare two or more numbers.
The exponent tells how many times the base is used as a factor.
A Greatest Common Factor (GCF) is used to compare two or more numbers. A single number cannot have a Greatest Common Factor.
A single number cannot have a highest common factor. A highest common factor is used to compare two or more numbers.
The least common factor of any set of numbers is 1.
A factor or a divisor. Both words are used depending on the textbook. I believe factor is more common in UK.
You cannot find the lowest common factor of a single number - lowest common factor is used as a comparison of two or more numbers.
We could have really used that other number. Without that, the answer will be one of the factors of 28.
The exponent tells how many times the base is used as a factor.
121: 11-11 132: 2-2-3-11 Great common factor: 11 Method(s) used: # (used) The method to find the greatest common factor of numbers is to find the prime factorizations of each one, select all matching prime factors, and then multiply. # An alternative method is to find all of the factors of each, and then select the greatest number that appears in each list. # The final method only applies to some numbers; if one of the number is a factor of the other, then that number is the greatest common factor. This is because all numbers are factors of themselves, and that is their greatest factor. If it is also a factor of the other number, then it is definitely the greatest common factor.
The word "common" means "same for all". There's nothing common about a single thing, There's no common factor of a single number. Before you can start looking for common factors, you need at least 2 different numbers.
