1 and 12, 3 and 4, and a few more
12 and 18
None. The LCM of two (or more) numbers is at least as large as the numbers. This means that the LCM must be larger than the smallest of the set of numbers and so the LCM cannot go into it.
The LCM is 12.
The LCM for the numbers 12 and 15 is: 60
The LCM of a set of prime numbers is their product.
The LCM of a set of numbers can never be smaller than the largest number in the set.
The LCM of 10 and 12 is: 60The LCM of a set of numbers is their product divided by their greatest common factor. The GCF of any two consecutive even numbers is 2, so the LCM of 10 and 12 is 10*12/2 = 60.It is: 60
The LCM is not defined for any set of numbers that contains a zero.
The LCM of 12, 84 is 84.
The LCM of 4 and 12 is 12. 12 is a multiple of 4 and of itself so it is the least common multiple.
The LCM will never be less than the GCF of a set of numbers.
The LCM of two numbers will never be less than the GCF.
