Yes, the GCF of any set of numbers must be less than or equal to the smallest member of the set. It cannot be greater. In this case, it is not 16 so it is less than 16.
It can be and is.
-14 = -1*1428 = 2*14Thus the GCF is 14. Do not be inclined to believe that the GCF is -14. Although -14 may be a common factor, it is less than 14, hence not the greatest common factor.

The least common factor of any set of numbers is 1.
Short answer: There is none. There are not common factors of a single number because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. Thus, there cannot be a single number that has the greatest number of common factors.
Yes, the greatest common factor of 16 and 42 can be and is less than 16. The GCF of 16 and 42 is 2..
It can be and is.
Yes, the greatest common factor is less than or equal to the smallest coefficient. For example, the greatest common factor of 38 and 8 is 2.
It can be and it is.
It can and is.

It isn't.
If we are trying to find the two numbers less than 50 with the greatest common factor, we need to pick two numbers with a larger difference between them, since the greatest common factor between two numbers cannot be greatest than the difference between the two numbers. To create a large difference, we will want one number to be close in value to 50. And, for the greatest common factor, we want the other number itself to be the greatest common factor. The greatest common factor that the larger number can have (since it is larger and thus cannot be the greatest common factor itself) is the number which is half its value. So, if we choose the even number closest in value to 50, we get 48. Then, if we take half of it, we get 24. The greatest common factor of 24 and 48 is 24. This is the largest possible greatest common factor of a pair of numbers less than 50.
Answer = 1Greatest common factor is largest number 37 or less they can both go into evenly.
Since 16 is not a factor of 40, the GCF must be less than 16.
When they have a factor in common greater than one.
