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.
19
Assuming this is the answer to a division sum, that depends entirely what the divisor of the sum is.
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 divisor is the number your dividing by, for an example (345 divided 8), 8 is the divisor. For another example as (2348 divided by 56), 56 is the divisor.
The Greatest Common Divisor is 19
The Greatest Common Divisor of 38, 57 is 19.
Three. 57/3=19
Since 1 has only one divisor - itself - the GCD of the two numbers must be 1.
