How to Find the LCM of 1 and 121 by Listing Common Multiples
The first step to this method of finding the Least Common Multiple of 1 and 121 is to begin to list a few multiples for each number. If you need a refresher on how to find the multiples of these numbers, you can see the walkthroughs for those here:

Let’s take a look at the first 10 multiples for each of these numbers, 1 and 121:
First 10 Multiples of 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
First 10 Multiples of 121: 121, 242, 363, 484, 605, 726, 847, 968, 1089, 1210
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 1 and 121 are 121, 242, 363. Because 121 is the smallest, it is the least common multiple.
The LCM of 1 and 121 is 121.
