JavaScript
const gcd = (a, b) => b === 0 ? a : gcd(b, a % b);
const lcm = (a, b) => Math.abs(a / gcd(a, b) * b);
console.log(lcm(12, 18)); // 36
TypeScript
const gcd = (a: number, b: number): number => b === 0 ? a : gcd(b, a % b);
const lcm = (a: number, b: number) => Math.abs(a / gcd(a, b) * b);
console.log(lcm(12, 18)); // 36
Python
from math import gcd
a, b = 12, 18
print(abs(a // gcd(a, b) * b))  # 36
Java
long a = 12, b = 18;
long gcd = java.math.BigInteger.valueOf(a).gcd(java.math.BigInteger.valueOf(b)).longValue();
System.out.println(Math.abs(a / gcd * b)); // 36
C#
long a = 12, b = 18;
long gcd = System.Numerics.BigInteger.GreatestCommonDivisor(a, b);
Console.WriteLine(Math.Abs(a / gcd * b)); // 36
