There can be only one GCF. 5 and 12 are coprime so GCF(5, 12) = 1
The GCF is 1.
The GCF of 5 and 10 is 5. The GCF of 4 and 12 is 4.
The GCF of 12 and 20 is 4.
GCF(145, 60) = 5.
There can be only one GCF. 5 and 12 are coprime so GCF(5, 12) = 1
The GCF is 1.
The GCF is 1.
The GCF is 1.
Since 4 and 5 are coprime, GCF(4, 12, 10, 5) = GCF(4,5) = 1
The GCF is 1.
The GCF of 5 and 10 is 5. The GCF of 4 and 12 is 4.
The GCF of 5 and 12 is 1. Factors of 5 are 1 and 5 Factors of 12 are 1, 2, 3, 4, 6, and 12 So the GCF is 1.
The GCF of 12 and 20 is 4.
GCF(145, 60) = 5.
