27 and 81 are a possibility. Also numbers like 5 and 10, 20 and 40.
Two numbers whose greatest common factor (GCF) is 20 are any pair of numbers that are multiples of 20. For example, 20 and 40 have a GCF of 20 because 20 is a factor of both numbers. Another pair could be 60 and 80, as 20 is also a factor of both of these numbers.

14 and 28 are two even numbers between 10 and 30 whose greatest common factor is 14.
There are several possibilities of pairs of numbers whose greatest common factor is 18. 54 and 198 18 and 126 414 and 846 72 and 1422
12 and 20
The GCF is 16.
The only common factor between 25 and 48 is 1. Therefore, it is RELTIVELY PRIME which is 2 or more nonzero whole numbers whose greatest common factor is 1.
