If a = 2 × 2 × 3, B = 2 × 3 × 3, then the greatest common factor of a and B is______ The least common multiple is______ .

If a = 2 × 2 × 3, B = 2 × 3 × 3, then the greatest common factor of a and B is______ The least common multiple is______ .

Number a = 2 × 2 × 3, number b = 2 × 3 × 3, then the greatest common factor of number a and number B is 2 × 3 = 6, and the least common multiple is 2 × 3 × 2 × 3 = 36, so the answer is 6, 36
