No, as LCM deals with two or more numbers. The only way for it to be one is if you only had 1. But you can't find the LCM of a single number, there must be two or more. So, there is no LCM of 1.
The LCM is: 9
The LCM is 40.
The LCM is 42.
The LCM is 21.
You can't find the LCM of a single number. The LCM of 1, 2, 3 and 14 is 42.
LCM(4, 1) = 4
Since 40 is a multiple of 1, it is automatically the LCM.
The LCM of 1 and 7 is 7.
The LCM of 1, 1 and 2 is 2.
The LCM is x^2 - 1.
It can be. 2 is the LCM of 1 and 2.
1 can only be an LCM (least common multiple) if the numbers you're trying to find an LCM for are 1 and 1. LCM cannot be smaller than the largest of the numbers you're using.
