1 and 2 are the only common factors of 8 and 18.
The GCF of 8 and 18 is 2. The factors of 8 are 1, 2, 4, and 8. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors are 1 and 2, so 2 is the greatest common factor. You can also look at the prime factors to determine the GCF. The prime factors of 8 are 2, 2, and 2. The prime factors of 18 are 2, 3, and 3. The prime factors in common are a single 2, so the greatest common factor is 2.

The common factors of 18 are: 1,2,3,6,9,18.
The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The common factors are 1, 2, 3, and 6. The greatest common factor is 6.
Common factors of 18 and 24 are: 1, 2, 3, and 6.
The greatest common factor of 48 and 18 is 6.This is because...6*8 = 486*3 = 18
Factors of 18 are 1, 18, 2, 9, 3, 6. Factors of 72 are 1, 72, 2, 36, 3, 24, 4, 18, 6, 12, 8, 9. So, Common Factors of both are: 1, 2, 3, 6, and 18. 18 is the GCF.
The factors of 18 are: 1, 2, 3, 6, 9, 18 The factors of 64 are: 1, 2, 4, 8, 16, 32, 64 The common factors are: 1, 2 The Greatest Common Factor: GCF = 2
