Method

longlcm(long a, long b)

Returns the least common multiple of the absolute value of two numbers, using the formula lcm(a,b) = (a / gcd(a,b)) * b . 

if (a == 0 || b == 0) {
    return 0;
long lcm = FastMath.abs(ArithmeticUtils.mulAndCheck(a / gcd(a, b),
        b));
if (lcm == Long.MIN_VALUE) {
    throw new MathArithmeticException(
            LocalizedFormats.LCM_OVERFLOW_64_BITS, a, b);
