1, if a is a multiple of B, then the least common multiple of a and B is B. () right and wrong 2, 3 is the greatest common factor, 12 is the least common multiple The least common multiple of 3, 6 and 8 is 24, the least common multiple of 16 and 12 is 48, so the greatest common multiple of two numbers must be greater than the two numbers themselves 4. The least common multiple of two numbers must be greater than the greatest common factor of this number

1. Wrong should be that a is the least common multiple of a and B. wrong topic does not say whose greatest common factor is whose least common multiple
2. Can't understand
3. Error can also be equal to one of the numbers, such as 3 and 12
4. Wrong. If two numbers are equal, then the greatest common multiple can be equal to the least common multiple
