What are the Multiples of 1?

Let’s take a look at the first 10 multiples for each of these numbers, 68 and 1:

First 10 Multiples of 68: 68, 136, 204, 272, 340, 408, 476, 544, 612, 680

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 68 and 1 are 68, 136, 204. Because 68 is the smallest, it is the least common multiple.

The LCM of 68 and 1 is 68.
