Java Utililty Methods lcm

double largerValue = a;
double smallerValue = b;
if (b > a) {
    largerValue = b;
    smallerValue = a;
for (int i = 1; i <= largerValue; i++) {
    if ((largerValue * i) % smallerValue == 0) {

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;
int lcm = Math.abs(mulAndCheck(a / gcd(a, b), b));
return lcm;

int c = gcd(a, b);
if (c == 0) {
    return 0;
return a / c * b;

if (a == 0 || b == 0)
    return 0;
return Math.abs(a / gcd(a, b) * b);

int ret = a / gcd(a, b) * b; 
return (ret < 0 ? -ret : ret);

return a * (b / gcd(a, b));

return a * b / gcd(a, b);

int temp = gcd(a, b);
return temp > 0 ? (a / temp * b) : 0;

return b * a / gcd(a, b);

return Math.abs(mulAndCheck(a / gcd(a, b), b));
