Solution is 2.
The GCF is 2.
The GCF is 2.
The Greatest Common Factor of 44, 42, 3: 1
The GCF of 1218 and 42 is 42. The GCF of 12, 18 and 42 is 6.
The GCF is 21.
The GCF is 4.
There cannot be a greatest common factor 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 GCF of 18 and 42 is 6. The GCF of 42 and 56 is 14.
The GCF is 2.
The GCF is 1.
The GCF is 1.
GCF(72, 44) = 4.
