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.
Oh, dude, that's like asking me to find a needle in a haystack... if the haystack was made of numbers. So, a number that's a factor of 30 means it divides evenly into 30, right? And being a multiple of 2 just means it's, like, even. So, the number you're looking for is 2 because it's, like, the cool kid that fits both criteria.
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.
