Question

what is the lcm of two numbers if one number is a multiple of the other. Give an example

Answer 1

The LCM of these two numbers would be the number that is the multiple of the other. 

For example:

The LCM of 8 and 56 is 56 because 8 is a factor of 56 and can  go into 56 seven times, and 56 is a factor of itself.
