No need to answer it anymore.
They are all composite numbers whose GCF is 1
4 and 8.
52 is composite. You need at least two numbers to find a GCF.
One
Any two composite numbers who do not share the same prime factors.15 = 5x322 = 11x2So 15 and 22 have a GCF of 1
10,20
4 and 9 have a GCF of 1
12 & 16
25, 49 and 121
They could be 12 and 18
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.
52 is composite. You need at least two numbers to find a GCF.

12 and 16
