There are not a greatest common factor, a least common factor, or common factors of a single number, such as 57, 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. Thus, since there are not two or more numbers to compare, there are no common factors.
The least common factor of any set of integers is 1.
It is 1 but the highest common factor is 19
The least common factor of any set of integers is 1.
The least common factor of any set of positive integers is 1.
The least common factor of any set of integers is 1.
The least common factor of any set of integers is 1.
The factors of 57 are 1, 3, 19, and 57. For them to be common, they need to be compared to another set of factors. You need at least two numbers to find a GCF.
The greatest common factor of 36 and 57 is 3.
The greatest common factor of 48 , 57 = 3
The greatest common factor of 24 and 57 is 3.
The greatest, and only, common factor of 57 (=3x19) and 28 (=22x7) is 1.
Greatest common factor of 57 and 102 is 3.
