Question

Write a function gcd(x, y) that returns the greatest common divisor of the parameters x and y. Use the Euclidean algorithm to do this. Return None if the gcd does not exist(i.e., if both parameters are 0)

Answer 1

function gcd(x,y) {

if (!y && !x) return 'None';

if (!y) return x;

return gcd(y, x%y);

}

console.log(gcd(462, 910));

console.log(gcd(0, 0));

console.log(gcd(32, 40));
