you need two numbers to have a greatest common factor
The GCF is 1.
109 is a prime number. The only two factors of a prime number are 1 and itself.The two factors of 109 are 1 and 109. There are only two factors of a prime number.The only factor pair of 109 is 1 x 109. There is only one factor pair of a prime number.The proper factors of 109 are only 1 or,if the definition you are using excludes 1, there are none.The only prime factor of 109 is 109. There is only one prime factor of a prime number - itself.The distinct prime factor (listing each prime factor only once) of 109 is also 109.The prime factorization of 109 is 109. In some cases, to emphasize that it is prime, you might write the prime factorization as 1 x 109.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.

The greatest factor that two or more numbers have in common is known as the greatest common factor, or GCF.
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor is the largest factor common to two or more numbers.
The Greatest Common Factor (GCF) is: 8
The greatest common factor is 2
The greatest common factor of 42 and 12 is 6.
No. The Greatest Common Factor (GCF) is the greatest factor that is in common with the numbers you are given.
The least common factor is always one (1), regardless of what the greatest common factor is.
