The answer is one, because 89 is a Prime number, and is not a factor of 95.
GCF(95, 89) = 1: the numbers are co-prime.
The GCF is 1.
The GCF is 1.
The GCF is 1.
The GCF is 1.
The GCF is 1.
The GCF is 95.
The GCF for 89 47 is 1.
gcf(89, 62) = 1.
The GCF of 89 and 1000 is 1.
The GCF is 5.
The GCF is 1.
