479 and 958.
The 2 smallest numbers that have GCF of 479 are 479 and 958.479 x 1 = 479479 x 2 = 958
479 and 479
2 and 3 are relatively prime, so multiply 479 by each of them to get two numbers that have 479 as a greatest common factor and are not divisible by each other, one which will be even and one which will be odd.479 x 2 = 958479 x 3 = 1437Furthermore, this is the smallest solution. The two numbers are multiples of 479, so let's call them 479x and 479y, where 479x is even and 479y is odd. Then x must be even, and y must be odd. So x is at least 2. y is an odd number, and it can't be 1 otherwise 479y would be a factor of 479x. So y is at least 3. Theefore the two numbers are at least 479*2 and 479*3.
479 and 958
958 and 1437
The two numbers can be 479 and 958 (479 doubled). 958 only has the factors 479 and 2, so, since 2 does not factor into 479, the common factor remains 479.
958 and 1437
1 is.
A single number cannot have a greatest common factor because "common" refers to factors that two or more numbers have in common. You have only one, which is 479. Also, only one number can be the greatest.

2 AND 3
479 is a prime number. Numbers having a greatest common factor of 479 are 479 and 958, or any other two or more multiples of 479.
