They are useful in finding the least common denominators.
Actually, they are useful. At least in some cases.
Color and streak would be the least useful, because they may be shared by a multitude of other minerals.
Density is the least useful property for identification because different specimens of the same type of mineral can vary in size. -Color is the least useful property for identification because it is the most obvious property.
Humans use gold for a variety of reasons, not the least of which is the jewelry industry. Gold has historically been used as currency or as a backing for currency. Gold is also used in electronics and audio components.
Color and streak would be the least useful, because they may be shared by a multitude of other minerals.
It's not useful. The least common factor is always 1.
Least common denominator.....
Color is the least useful property for identifying minerals because it can vary within the same mineral species, making it less reliable for accurate identification. Other properties like hardness, cleavage, and luster are more consistent and helpful in distinguishing between different minerals.
Factors are useful when you're trying to reduce fractions. Multiples are useful when you're trying to find a least common denominator.
Color is generally the least useful characteristic in identifying minerals, as many minerals can come in a variety of colors. Other properties, such as hardness, streak, cleavage, and specific gravity, are more reliable indicators for identifying minerals.
