There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
The greatest common factor of 58 and 174 is 58.
The greatest common factor of 16 , 58 = 2
The greatest common factor of 36 , 58 = 2
The GCF of 42 and 58 is 2.
Greatest Common factor for 58 and 84 is 2.
The greatest common factor of 58 and 81 is 1.
The greatest common factor of 58 , 17 = 1
The greatest common factor of 22 and 58 is 2The GCF is 2.
Greatest Common Factor (GCF) of (35,58) is 1.
GCF of 29 and 58 is 29The GCF is 29.
The greatest common factor of the numbers 38 and 58 is 2.. 2 is the only common factor since 19 and 29 are both prime 2X19=38; 2X29=58
The Greatest Common Factor (GCF) of the numbers 58 60 is 2 because it is the greatest number that can be divided into the numbers.
