Final answer:
The LCM (Least Common Multiple) of a single number is the number itself, which means the LCM of 12680 is 12680. The options provided A, B, C, and D are not correct since none of them are 12680. The correct option is: C.3 k
Step-by-step explanation:
The question is asking for the Least Common Multiple (LCM) of a single number, which in this case, is 12680. However, the concept of LCM applies to at least two numbers, as it is the smallest positive number that is a multiple of two or more numbers. For a single number like 12680, the LCM is the number itself because it is the smallest multiple that the number has. Therefore, the LCM of 12680 is simply 12680.
To address the choices provided, none of them are correct in this context because they are all less than 12680. Thus, the LCM cannot be one of these options.
It's possible that there is a misunderstanding or typo in the question, as typically the LCM question includes two or more numbers. If more numbers were provided, we would need to find the smallest number that is a multiple of all given numbers. The correct option is: C.3 k
