Yes (12,18,24,30,36 etc)
3 yes, 6 no.
Because 3 is a factor of 6.
All multiples of 6 have 3 as a factor
Yes, but not all of them. Every multiple of 6 is also a multiple of 3, but there are more multiples of 3 besides those.
They are all multiples of 6
18 and all the multiples of 18.
Yes, multiples of 3 are also multiples of 6. This is because 6 is a multiple of 3, meaning it can be divided evenly by 3. Therefore, any number that is a multiple of 3 will also be divisible by 6. For example, 3, 6, 9, 12, etc., are all multiples of both 3 and 6.
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
Yes. Because 3 is half of 6 and will always go into it equally
3: 3, 6, 9, ... 6: 6, 12, 18, ... 18: 18, 36, 54, ... The lcm(3, 6, 18) = 18, so the multiples of 18 are common multiples of all of them.
The numbers 3,6 and 9 are all multiples of 3 because 3 can go into all of them evenly.
Yes they are - since 3 is a factor of 6.
