It is 1 because 19 is a prime number
find the factors of each # and then find the highest common factor: 18=1,2,3,6,9,18 19=1,19 gcd(19,18)=1
The greatest common factor of 19 and 38 is 19.
19 is a prime number, so the GCD is 1 * * * Right answer, wrong reason. 19 is indeed a prime but the GCD of 19 and 38, for example, is not 1.
The greatest common factor of 76 and 95 is 19.The factors of 76 are 1, 2, 4, 19, 38 and 76.The factors of 95 are 1, 5, 19 & 95.Therefore the greatest common factor is 19.
Same as the greatest common factor of 19 and 18 - where 18 is the remainder of the division of 94 by 19.
