greatest common divisor js code example

Example 1: javascript gcd

const gcd = (a, b) => b === 0 ? a : gcd(b, a % b);

// Example
gcd(10, 15);    // 5

Example 2: get gcf javascriot

function gcd_two_numbers(x, y) {
  if ((typeof x !== 'number') || (typeof y !== 'number')) 
    return false;
  x = Math.abs(x);
  y = Math.abs(y);
  while(y) {
    var t = y;
    y = x % y;
    x = t;
  }
  return x;
}

console.log(gcd_two_numbers(12, 13));
console.log(gcd_two_numbers(9, 3));
