Each of the numbers goes into the LCM so the LCM must be at least as big as the number.
So if there are two numbers and their LCM is at least as big as either of them, it cannot be less than either.

Multiples can't be smaller than the original numbers. A number can't have a multiple smaller than itself.
Not always, sometimes the LCM equals the greatest number, i.e.the LCM of 5 and 6 is 30, the LCM of 3 and 6 is 6.
No.
If the two numbers do not have any factors in common (other than 1), then the LCM is the same as the product of the two numbers. Example: LCM of 5 & 6 is 30, which is the same as the product.
The LCM of 4 and 6 is 12.
No, the only way the GCF and LCM of two numbers can be the same is if the numbers are the same.
