No, it is not.
No, the answer is exactly 8071.5
No, 130 is not a multiple of 4 and 4 is not a multiple of 130.
Any multiple of 4 is also a multiple of 2.
Any multiple of 20 is also a multiple of 4.
4 and any multiple of 4
No, 51 is not a multiple of 4.
No - but 4 IS a multiple of 8 !
No. 426 is not a multiple of 4
176 is a multiple of 4. 176 is a multiple of 11. That makes it a common multiple of 4 and 11.

No, but vice versa holds true. Case and point: 6 is a multiple of 2, but not a multiple of 4. 8 is a multiple of 4, and is a multiple of 2. Because a factor of 4 is 2, every multiple of 4 is also a multiple of 2. But since 4 is not a factor of 2, rather, only half of it, only half of the multiples of 2 will be multiples of 4.
