False, they're rarely equal.
GCF of 12 and 4 is 4
LCM of 12 and 4 is 12
False
It is false.
True.
TRUE
LCM and GCF are almost never equal.
By definition, an even number has 2 as a factor. That means that any set of even numbers will have at least a common factor of 2. Since that common factor will also have 2 as a factor, it has to be even.
GCF - Greatest Common Factor (GCF is always smaller or equal to at least one of the numbers) LCM - Least Common Multiple (LCM is always greater or equal to at least one of the numbers)
No
Hardly ever.
Yes, that is true.
Yes.
When the denominators are relatively prime, that is, they have a GCF of 1.
