The first step to this method of finding the Least Common Multiple of 74 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:

Let’s take a look at the first 10 multiples for each of these numbers, 74 and 1:

First 10 Multiples of 74: 74, 148, 222, 296, 370, 444, 518, 592, 666, 740

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 74 and 1 are 74, 148, 222. Because 74 is the smallest, it is the least common multiple.

The LCM of 74 and 1 is 74.
