GCF =1

Explanation:

2 and 5 are prime numbers, so the only factor they have in common is 1

6 shares the factor of 2 with 2, but apart from 1 has no common factor with 5

The following are the products of the factors;

2 =1xx2
5 =1color(white)(wwwww)xx5
6 = 1xx2xx3

It is clear that the only factor they have in common is 1
