The only such number is 1.
No.
Yes, 66/3 = 22
YES
1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
Starting with the numbers 22, 66, and 110, 22 divides into 66 evenly 3 times and into 110 evenly 5 times, so the greatest common factor between those three numbers is 22.
no numbers!
These will: 1, 2, 3, 6, 11, 22, 33, 66.
Nothing can go evenly into 21 or 17. They are both odd numbers and therefore cannot be evenly divided.
The numbers that go into 30 are1, 2, 3, 5, 30, 15, 10, 6
1, 2, 3, and 6 can
This is the same as asking, "what are the multiples of 66". There are an infinite number of multiples. The first is 66 (66 * 1), the second is 132 (66 * 2) and this continues on for ever.
