The first step to this method of finding the Least Common Multiple of 98 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, 98 and 1:
First 10 Multiples of 98: 98, 196, 294, 392, 490, 588, 686, 784, 882, 980
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 98 and 1 are 98, 196, 294. Because 98 is the smallest, it is the least common multiple.
The LCM of 98 and 1 is 98.
