2, 7, and 14
42 - 28 = 14
28+14 = 42 42-14= 28
42-28 = 14
GCF(14, 28, 42) = 14.
LCM of 14 28 42 is 84.
gcf(14, 28, 42) = 14.
7x6=42 7x4=28
The GCF is 14.
The greatest (highest) common factor of 28 and 42 is 14.The GCF is 14.
28+14=42, But 28 x 14=392, Therefore the answer is NO!
The greatest common factor of 28 and 42 is 7
28
