List the factors of each number. The largest factor they have in common is the GCF.
16: 1, 2, 4, 8, 16
40: 1, 2, 4, 5, 8, 10, 20, 40
48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The largest factor they have in common is 8, so the GCF is 8.
The GCF is 8.
8the GCF of 40 and 48 is 8The GCF is 8.8
The GCF is 16.
The GCF is 8.
The GCF is 16.
Since 16 is a factor of 48, it is automatically the GCF.
The GCF is 16.
