Answer:
There is no greater common factor for the given numbers.
Step-by-step explanation:
The greatest common factor (GCF) is the largest positive integer that would divide a set of given numbers without a remainder.
Considering the factors of each number,
25 = 1 × 5 × 5
5 = 1 × 5
11 = 1 × 11
and
23 = 1 × 23
52= 2 × 2 × 13
7 = 1 × 7
Comparing the factors, there is no gcf among the given numbers.
