12 and 16
Not necessarily.
The GCF of 6 and 10 is 2.
the two smallest numbers are 49 and 14
4 and 8
10,20
They could be 12 and 18
No need to answer it anymore.
12 and 16
52 is composite. You need at least two numbers to find a GCF.
One
12 and 16
Any two composite numbers who do not share the same prime factors.15 = 5x322 = 11x2So 15 and 22 have a GCF of 1
Any two coprime numbers
Not necessarily.
The GCF of 6 and 10 is 2.
15 and 30
