The 12x on a zoom camera means the digital cropping of an image which is enlarged in size. This creates the illusion of a zoom effect. So basically the lens can crop forward to get a closer look of something 12x.
I usually see anywhere from 6x to 12x optical zoom, then most digital cameras also have digital zoom, up to about 20x

GCF = 12x.24x = 2(12x)36x3 = 3x2(12x)
2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667
