The GCF is 1.
The GCF is 1.
The GCF of 5 and 10 is 5. The GCF of 4 and 12 is 4.
The GCF is 1.
The GCF of 4, 5, and 8 is 1. Since 4 and 5 are consecutive integers, their GCF is 1.
Since 4 and 5 are coprime, GCF(4, 12, 10, 5) = GCF(4,5) = 1
The GCF is 1.
The GCF is 1.
Since 4 is a factor of 20, it is automatically the GCF.
