lcm

Returns the least common multiple of two numbers.

Use the greatest common divisor (GCD) formula and Math.abs() to determine the least common multiple. The GCD formula uses recursion.

const lcm = (x, y) => {
  const gcd = (x, y) => !y ? x : gcd(y, x % y);
  return Math.abs(x * y) / (gcd(x, y));
};

lcm(12,7) // 84
