You need at least two numbers to find an LCM.
If that's 81 and 215, the LCM is 17415.
If that's 8, 12 and 15, the LCM is 120.
They are all multiples.
The least common factor of any group of whole numbers is always 1. You need to have at least two numbers to have a math problem. Since there is only one number, there cannot be a least common factor.
Least common multiples 12 and 16 is 48.
The least common multiples of 7 and 14 are 14,28 and 42>
The least common multiples of the number 6 and 9 is 3.
The least common multiples of 5, 11, and 13 is 715.
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
3 Least Common Multiples of 12 and 35 are 420, 420 and 420.There is ONLY one Least Common Multiple.The three common multiples of 12 and 35 which are the smallest are the first three multiples of their Least Common Multiple, namely 420, 840 and 1260
You need at least two numbers to compare multiples.
It is 12 and its multiples.
The common multiples of 9 and 16 are 144, 288, 432 and so on.
Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
