The GCF is 1.
' 1 ' is.
The GCF is 3.
The GCF of 15 and 90 is 15.
Since 15 is a factor of 60, it is automatically the GCF.
The GCF is: 1
gcf(15, 9, 19) = 1.
The gcf of 6, 15, and 21 is 3. But once you throw that 19 in there, it's ' 1 '.
75 = 3 * 5 * 5 and 285 = 3 * 5 * 19 they have in common ( 3 * 5) So the GCF is 15.
The GCF is 19.
The GCF is: 19
