Yes.
You need at least two numbers to find an LCM, it will divide by those numbers.
The smallest number that is a multiple of two given numbers is called the least common multiple (LCM) of those two numbers. It can be found by taking the product of the two numbers and dividing it by their greatest common divisor (GCD).
No, the only way the GCF and LCM of two numbers can be the same is if the numbers are the same.
Yes. If one number is a factor of the other, the greater number will be the LCM of the two.
The LCM of those two numbers is 80000000000.
Numbers that are relatively prime.
Yes.
The LCM of two numbers is one of the numbers when one of the numbers is a multiple of the other. The LCM of two numbers is the product of the numbers when they are relatively prime. In all other cases (like consecutive even numbers that aren't 2 and 4) the LCM is as you describe.
You need at least two numbers to find either of those.
They are relatively prime.
When one of two numbers is a multiple of the other, the LCM is the larger number.
The LCM of one number is itself. LCM involves two or more numbers.
The LCM is the larger number.
The LCM of one number is itself. LCM requires two or more numbers to solve for the LCM.
The LCM is the one that is the multiple.
The LCM of one number is itself. LCM involves two or more numbers.
