Quantity A | Quantity B | |
---|---|---|

The least common multiple of 22 and 6 | The greatest common factor of 66 and 99 |

I have tried using Greg’s method : Doing prime factorization

For LCM: get the numbers that are higher

For GCF: get the numbers that are lower in exponents

I got both answers as 66. So, C option but the answer is A. How?
