Any multiple of 3.
Yes, because 3 is a factor of 6 and therefore is a factor of any number for which 6 is a factor.
It is 3 that is a common prime factor to both numbers
They are 33 and any of its multiples
The factor numbers are 3 and -17.
Any number that is a multiple of 3 has 3 as a factor.
There are an infinite number of numbers with 3 as a factor. Any number evenly divisible by 3 has 3 as a factor. That means 6, 9, 12, 15, 18, ..., all have 3 as a factor.
