The numbers 2 and 6 meet both conditions.
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.
6 is a factor of 30 and a multiple of 2.
The factors of 18 are 1, 2, 3, 6, 9 and 18. None of them are multiples of 5.
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.
No, 18 is a multiple of 9. (18 = 2 x 9, so 2 and 9 are factors of 18).
2
3 and 9 both work
2 is a factor of 14 but not a multiple of 7.
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
