You can but you don't need to. Since 30 and 7 don't have any common prime factors, their LCM is their product, 210.
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.
Use some method which you probably already learned, to find the least common multiple. All the other common multiples are multiples of this least common multiple, so you can multiply the least common multiple by 2, by 3, by 4, etc., to get additional common multiples.
You can't find the Common Multiple of only one number. You need at least two numbers to find the common multiples.
All sets of numbers have common multiples. It is sometimes advantageous to find the smallest of these. This is known as the least common multiple or LCM.
You need at least two numbers to find a least common multiple.
You can not find the least common multiple of just one number. You can find the multiples of 147 but have nothing to compare it to to find the "least" first 6 multiples of 147 - 147, 294, 441, 588, 735, 882
You can't find the Common Multiple of only one number. You need at least two numbers to find a common multiple.
The Least Common Multiple (LCM) of3, 16, and 20 is 240.
To find the lowest common multiple you must have at least two numbers.
You can't find the Least Common Multiple (LCM) of only one number. You need at least two numbers to find the LCM.
To find the lowest common multiple you must have at least two numbers.
Since this is a single number, you could say that it shares all of its multiples with itself. So the least multiple of the number is itself. However, determining a least common multiple generally requires at least two numbers from which to find the LCM.
