The GCF is 1.
The GCF is 2.It is: 2
The GCF is 2.
The factors of 14 are:1, 2, 7, 14The factors of 21 are:1, 3, 7, 21The factors of 81 are:1, 3, 9, 27, 81The Greatest Common Factor (GCF) is:1
GCF(14, 28, 21) = 7
The greatest commonfactor(gcf) of 24 and 21 is 3
Since 7 is a factor of 14, it is automatically the GCF.
