18 is not a prime number so no number can have 18 as a prime factor.
18 is a composite number because it has at least one positive factor other than one or itself.
The LEAST Common FACTOR of any set of numbers is 1. There is the Least Common MULTIPLE which is the smallest number which is a multiple of both. For 26 and 18 the LCM is 234 There is the GREATEST Common Factor which is the greatest number which is a factor of both. FOr 26 and 18 the GCF is 2.
Not a factor of 18 ?
It can be. 9 is a factor of 18.
18 is a factor of 36. 36 is a square. 18 is not.
18 is a single number. The factor pairs of 18 are (18,1)(9,2)(6,3)
18. All numbers' highest factor is the number itself.
The number 8 is the factor of 18. But 8 is not a multiple of 6.
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.
