The first step to this method of finding the Least Common Multiple of 141 and 1 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:
What are the Multiples of 141?
Let’s take a look at the first 10 multiples for each of these numbers, 141 and 1:
First 10 Multiples of 141: 141, 282, 423, 564, 705, 846, 987, 1128, 1269, 1410
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 141 and 1 are 141, 282, 423. Because 141 is the smallest, it is the least common multiple.
The LCM of 141 and 1 is 141.
