52 is composite. You need at least two numbers to find a GCF.

Any two composite numbers who do not share the same prime factors.15 = 5x322 = 11x2So 15 and 22 have a GCF of 1

The GCF of 24 and 36 is 12. The GCF of 60 and 96 is 12. The GCF of 12 and 120 is 12.

Without specifying the GCF, it could be anything. 9 and 12 have a GCF of 3.

240, 480 and 7200

4 and 9 have a GCF of 1

12 & 16

They could be 12 and 18

25, 49 and 121

They are all composite numbers whose GCF is 1

12 and 16

4 and 8.

The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.
