Weight = m g
Mass = Weight / g = 39.2 / 9.8 = 4 kg
392 56 x 7 = 392
√392 ~= 19.799
Yes. 19.7989 is the square root of 392. But 392 is not a perfect square.
The LCM is 392.
The LCM of 1521 and 392 is 596232. The LCM of 15, 21 and 392 is 5880.
There are six factor pairs: 392 = 1 x 392 392 = 2 x 196 392 = 4 x 98 392 = 7 x 56 392 = 8 x 49 392 = 14 x 28
What planet are you on? I don't mean to be a wise-ass, but weight depends upon the acceleration of gravity, which is different on different planets, whereas mass is the same no matter where you are. On the surface of the Earth, the acceleration due to gravity is 9.8 m/s2, so a 40-kg mass will weigh 40 x 9.8 = 392 newtons.
392 56 x 7 = 392

If the mass of the barrel is 40 kilograms and the barrel is presently on earth, then it weighs 392 newtons (88.2 pounds). What you do with it, what dizzying gyrations you subject it to, or what other objects happen to be nearby, have no effect on its weight.
