Let’s take a look at the first 10 multiples for each of these numbers, 128 and 1:
First 10 Multiples of 128: 128, 256, 384, 512, 640, 768, 896, 1024, 1152, 1280
First 10 Multiples of 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
You can continue to list out the multiples of these numbers as long as needed to find a match. Once you do find a match, or several matches, the smallest of these matches would be the Least Common Multiple. For instance, the first matching multiple(s) of 128 and 1 are 128, 256, 384. Because 128 is the smallest, it is the least common multiple.
The LCM of 128 and 1 is 128.
