Unfortunately, the Beretta 682 shotgun is being used in video games to promote realistic effects. This attempt for reality has been a good selling point for gun enthusiasts.

I had a similar issue several years ago and finally had to take the ring to a jeweler. 682, or any 3 digit number stamped on a gold or silver ring, refers the purity of the metal. So in your case, .682 fine gold or 14k gold.
Year of manufacture is not in the SN, it's on the date code on the barrel but I'm guessing early 90's.
9% of 682= 9% * 682= 0.09 * 682= 61.38

It is not possible for 682 to go into 4 because 4 is smaller than 682.

1 meter = 100cm. So, 682 cm = 682 / 100 = 6.82 meters.
The GCF of 682 and 4800 is 2.
