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.
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.
is 2 divisor of 64
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.
