A = 2 × 3 × 5 × 7, B = 2 × 3 × 11, the greatest common factor of a and B is______ The least common multiple is______ .

A = 2 × 3 × 5 × 7, B = 2 × 3 × 11, the greatest common factor of a and B is______ The least common multiple is______ .

A = 2 × 3 × 5 × 7, B = 2 × 3 × 11, the greatest common factor of a and B is 2 × 3 = 6, the least common multiple is 2 × 3 × 5 × 7 × 11 = 2310; so the answer is: 62310
