It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
The Greatest Common Factor of 74 and 43 is 1.
One is the greatest common factor of 43 and 40.
The Greatest Common Factor of 23, 43, 35: 1
The GCF is 1.
The greatest common factor of 34 , 43 = 1
The GCF is 1.
The Greatest Common Factor of 14, 43, 49 is 1.
The Greatest Common Factor (GCF) is: 1
The greatest common factor of 43 , 16 = 1
The greatest common factor of 43 and 49 is 1, since no other factor is shared between the two.
43 has no factors except 1 and 43.So the greatest common factor of 43 and any multiple of 43 is 43, andthe greatest common factor of 43 and any non-multiple of 43 is 1.
The Greatest Common Factor (GCF) of (2,43) is 1.
