Yes, the greatest common factor is less than or equal to the smallest coefficient. For example, the greatest common factor of 38 and 8 is 2.
Yes, if that number is a factor of the other.
No.
Yes.
OK you list all the factors of each number and what ever number is the greatest and the same in both numbers that is the Greatest Common Factor Glad I could help!!!!!!!!!!!!!!!
47 is a prime number so the great common factor of 47 and any other number can only ever be 1.
No. The smallest coefficient possible is 1, and the smallest GCF is also 1. You cannot have a common factor of zero.
No. At most, it can be equal to the smaller number.
No. Odd numbers don't have even factors.
No. Zero is never a factor, except for maybe zero itself and that's a matter of definition that I don't know.
No, it is never bigger than the smaller number.
No, it is never bigger than the smaller one.
