Common factors of 18 and 24 are: 1, 2, 3, and 6.
The common factors of 56 and 18 are 1 and 2.
The factors of 18 are: 1, 2, 3, 6, 9, 18The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56The common factors are: 1, 2
Since 18 is a factor of 180, all of its factors are common.
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 16 are: 1, 2, 4, 8, 16The factors of 18 are: 1, 2, 3, 6, 9, 18The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24The common factors are: 1, 2
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.
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 and 18. For them to be common, they need to be compared to another set of factors.
