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

int lcm(int a, int b)
lcm

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

int lcm(int a, int b)
Least common multiple.

lcm( 6, 9 ) = 18
lcm( 4, 9 ) = 36
lcm( 0, 9 ) = 0
lcm( 0, 0 ) = 0

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

int lcm(int a, int b)
Returns the least common multiple of two integers.

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

int lcm(int a, int b)
lcm

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

int lcm(int a, int b)
lcm

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

int lcm(int a, int b)
lcm

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

int lcm(int a, int b)
Returns the lowest common multiple between a and b.

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

int lcm(int a, int b)
Returns the least common multiple between two integer values.

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