2 is a factor of 18 and is not a multiple of 3.
Yes 18 times 2 equals 36 It is a factor, not a [proper] multiple.
2 is the only number is that both a factor of 2 and a multiple of 2.
The factors of 18 are 1, 2, 3, 6, 9 and 18. None of them are multiples of 5.
All factors of 18 are factors of 36, because 18 itself is a factor of 36.
6 is a factor of 30 and a multiple of 2.
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.

The greatest common multiple of 10 and 18 is infinite.However, I suspect you want either:the greatest common factor of 10 and 18 which is the largest number which divides both 10 and 18 and is 2; orthe lowest common multiple of 10 and 18 which is smallest number into which both 10 and 18 divide (ie the smallest number which is a multiple of both 10 and 18) and is 90
The greatest common factor is 2 and the least common multiple is also 2.
The only prime factor of 4 is 2. No prime number is a multiple of 5.
