Diamond-like Carbon has a coefficient of friction of as low as 0.05 on polished steel.
It can never be exactly zero, but it is close to 0.
Yes but make sure you are clear in your understanding between the coefficient of friction and the force of friction. The force of friction is the force that resists the motion of two surfaces moving against one another. The amount of friction is determined by the product of the coefficient of friction and the normal (perpendicular) force that is pressing the two surfaces together. The coefficient of friction is a unit-less constant, that indicates how two surfaces compare to two other surfaces that are being pressed together the same amount. If the normal force is the same on two pairs of surfaces the pair of surfaces with the lowest coefficient of friction will experience the lower force of friction.
Yes.

NaCl, common table salt, has a rather high melting point. The substance with the lowest melting point is helium. Helium has no solid phase, it melts at any temperature above absolute zero.

The lowest common denominator is 12. The lowest common factor is 1.
2 is the lower number. And whether or not it is in friction (or possibly fraction) is irrelevant.
Lowest common factor=1Are you sure you don't mean lowest common multiple of highest common factor?Lowest common multiple=96Highest common factor=2
The lowest common multiple, or lowest common denominator, of 18 and 28 is 252.
Helium
The lowest common factor is always one.
