what is the greatest common factor and the least common multiple of?
Since 1 divides into everything, then the greatest common factor in this case is just 1. When 1 is the GCF, the numbers are said to be "relatively" prime; that is, they are prime, relative to each other. Then the GCF is 1 and the LCM is 2 × 2 × 2 × 3 = 24.
