18 has the following factors: 1, 2, 3, 6, 9, and 18. This is a total of 6 factors.
30 has the following factors,: 1, 2, 3, 5, 6, 10, 15 and 30. This is a total of 8 factors.
Therefore, 18 and 30 do not have the same number of factors.

The GCF of 18 and 30 is 6
18 is a single number. The factor pairs of 18 are (18,1)(9,2)(6,3)
The GCF is 3.
The GCF of a prime number and a composite number is 1 if the former is not a factor of the latter. 73 is a prime number and 18 is a composite number and 73 is not a factor of 18 because 18 is not divisible by 73. So, GCF(73, 18) = 1.
6, 18, 30, 90
1 and 3 are factors of all of them.
The Greatest Common Factor of 18, 27, and 30 is 3.
The Greatest Common Factor of 18, 24, 30: 6
The greatest common factor of the numbers 18, 30 and 72 is 6.
The GCF is 3.
Not a factor of 18 ?
No. The number 30 is composite and so it cannot be a prime factor.
The greatest common factor is 6.
GCF(30, 18) = 6.
