Any two or more prime numbers have 1 as the greatest common factor.
1 is the greatest common factor of any fraction in lowest terms.
The greatest common factor of any two consecutive integers is 1.
The Greatest Common Factor (GCF) is: 1 .The greatest common multiple of any set of integers is infinite.
The Greatest Common Factor (GCF) is: 1 .The greatest common multiple of any set of integers is infinite.
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as ??, 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 1 and 3 are only 1; the greatest common factor is 1. The common factors of 1 and 111 are only 1; the greatest common factor is 1. Note: Since the only factor of 1 is 1, when finding the greatest common factor of 1 and another number, the only possible common factor and greatest common factor is 1.
There can be only one greatest common factor for any set of numbers. In this case, it is 1.
The greatest common factor of 14 and 59 is 1.
The greatest factor of any number is the number itself. The greatest common factor of 71 and 92 is 1.
The greatest common factor (GCF) of 2990 and 1150 is 230.
The greatest common factor of 18 and 55 is 1.
The least common factor of any set of numbers is 1.
