The list of methods to do BigInteger LCM are organized into topic(s).

Method

BigIntegerlcm(BigInteger a, BigInteger b)
Least common multiple.
http://en.wikipedia.org/wiki/Least_common_multiple
lcm( 6, 9 ) = 18
lcm( 4, 9 ) = 36
lcm( 0, 9 ) = 0
lcm( 0, 0 ) = 0 
if (a.signum() == 0 || b.signum() == 0)
    return BigInteger.ZERO;
return a.divide(a.gcd(b)).multiply(b).abs();
BigIntegerlcm(BigInteger a, BigInteger b)
lcm 
return a.multiply(b).divide(gcd(a, b));
BigIntegerlcm(BigInteger... nums)
lcm 
return lcm(Arrays.asList(nums));
BigIntegerlcm(BigInteger... values)
Calculates the least common multiple of the specified BigInteger big integer numbers. 
if (values.length == 0)
    return BigInteger.ONE;
BigInteger lcm = values[0];
for (int i = 1; i < values.length; i++) {
    if (values[i].signum() != 0) {
        final BigInteger gcd = lcm.gcd(values[i]);
        if (gcd.equals(BigInteger.ONE)) {
            lcm = lcm.multiply(values[i]);
