8 and 16

You can't name the greatest common factor of a single number. You need at lest two numbers to find a GCF.In order to have a GCF there must be two or more numbers.The factors of 64 are 1, 2, 4, 8, 16, 32, 64.

There are many possible pairs. 8, 904 160, 168 256, 328 24, 5320

2x and 6x

Any numbers that don't have common prime factors will do; for example, 23 and 32; 2x3 and 5x7, 3x5 and 2x7, etc.Any two consecutive numbers will have no common factor, for example, 8 and 9 (the first example I gave above), or 100 and 101. However, in the second example, 101 is not a composite number.

The greatest common divisor is another name for the greatest common factor (GCF) and refers to the largest number that will divide into two or more numbers evenly with no remainder.

5 and 10 5 and 15 5 and 20

200,205, 10

In that case, the smaller number is a factor of the larger one. The larger one is a multiple of the smaller one.

I thick it is 27 and 81

All numbers with a least common multiple, have that multiple as a factor.

27 and 81 are a possibility. Also numbers like 5 and 10, 20 and 40.
