2 and 1
They are all the multiples of 4.
All multiples of 4 are multiples of 2 and 4.
It's not. 4 is a multiple of 2. 2 is a factor of 4 because it can divide into 4 evenly with no remainder.
If ordered by size, only every other multiple of 2 is a multiple of 4. All multiples of 4 are multiples of 2.
Since 4 is a multiple of 2, all the multiples of 4 will be common.
Yes.
Yes.
Yes. In fact all even numbers (not just 4) will share their multiples with 2.
Because 6 is a multiple of 2 and not of 4.
because... 4 does not go into 2 so it's not a multiple All multiples of 4 are multiples of 2.
all numbers that are multiples of 4 have 2 as factor
4, 8 and 12 are the first 3 common multiples of 2 and 4
