They aren't. Try 40.
All multiples of 4 are multiples of 2 and 4.
Yes. In fact all even numbers (not just 4) will share their multiples with 2.
Any and all multiples of 60.
All multiples of 4 are also multiples of 2. e.g. 15 x 4 = 60. (60 is a multiple of 2 and 4) All multiples of 4 are even numbers. e.g. 4, 8, 12, 16, 18, 20, 24, 28 etc (these numbers all end in either 0,2,4,6, or 8.
All multiples MUST be multiples of 4.
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.
Yes.
Yes. In fact all even numbers (not just 4) will share their multiples with 2.
Since 4 is a multiple of 2, all the multiples of 4 will be common.
Because 6 is a multiple of 2 and not of 4.
yes. they are still multiples of 2
because... 4 does not go into 2 so it's not a multiple All multiples of 4 are multiples of 2.
No. All it needs is one counter example to disprove: 6 is a multiple of 2 but NOT a multiple of 4.
All multiples of 4; 4, 8, 12 and so on.
Because 20 is a multiple of 4. All multiples of 20 are also multipples of 2, 5 and 10
