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 factors of 18 are 1, 2, 3, 6, 9, and 18
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30
The common factors of 18 and 30 are 1, 2, 3, and 6
Every integer has factors. 30 has eight factors: 1, 2, 3, 5, 6, 10, 15 and 30.

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, 24, 30: 6
The Greatest Common Factor of 18, 27, and 30 is 3.
The greatest common factor of the numbers 18, 30 and 72 is 6.
The GCF is 3.
Not a factor of 18 ?
The greatest common factor is 6.
No. The number 30 is composite and so it cannot be a prime factor.
GCF(30, 18) = 6.
6
Yes. Any number is a factor of itself. 30 x 1 = 30.
