									private static int GCD(int a, int b)
{
	if (a == 0)
		return b;

	while (b != 0)
	{
		if (a > b)
			a -= b;
		else
			b -= a;
	}

	return a;
}

public static int LCM(int a, int b)
{
	return (a * b) / GCD(a, b);
}
								

Example

									int lcm = LCM(15, 12);
								

Output

									60
