A and B are also divisible by which of the following?ANSWER
wrongA number is divisible by another number (a divisor) if its prime factorization contains the prime factorization of the divisor.
The prime factorization of A is getPrimeFactorization( A ).join( "\\times" ).
The prime factorization of B is getPrimeFactorization( B ).join( "\\times" ).
So, any number divisible by both must have LCM_FACTORIZATION.join( "\\times" ) as part of its prime factorization.
All numbers which divide such a number will have a factorization which is part of LCM_FACTORIZATION.join( "\\times" ).
The prime factorization of ANSWER is getPrimeFactorization( ANSWER ).join( "\\times" ).
Since getPrimeFactorization( ANSWER ).join( "\\times" ) is part of LCM_FACTORIZATION.join( "\\times" ), all numbers which are divisible by A and B are also divisible by ANSWER.
