How do you list common multiples?
We can find the common multiples of two or more numbers by listing the multiples of each number and then finding their common multiples. For example, to find the common multiples of 3 and 4, we list their multiples and then find their common multiples. Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36.
What method did you use to find common multiples and the LCM of the given set of numbers?
Below is a list of the first eight multiples of 6. Notice that to find them, we will multiply 6 by the first eight elements of the set of counting numbers which are 1, 2, 3, 4, 5, 6, 7, and 8. The products become the first eight multiples of 6. Let’s go over more examples on finding the multiples of a number.
What is the formula for finding LCM?
The Least Common Multiple (LCM) of two integers a and b, usually denoted by LCM (a, b), is the smallest positive integer that is divisible by both a and b….Formula of L.C.M.

| L.C.M formula for any two numbers | L.C.M. = a×bgcd(a,b) |
Why do you need to find the least common multiple?
In math problems where we pair two objects against each other, the LCM value is useful in optimizing the quantities of the given objects. Also, in computer science, the LCM of numbers helps design encoded messages using cryptography.
What’s the least common multiple of 20 and 15?
60
Answer: LCM of 15 and 20 is 60.
What is the least common multiple of 2 and 8?
8
What is the LCM of 2 and 8? Answer: LCM of 2 and 8 is 8.
How do you find the least common multiple using a table?
To find the LCM by division method, we write the given numbers in a row separately by commas, then divide the numbers by a common prime number. We stop dividing after reaching the prime numbers. The product of common and uncommon prime factor is the LCM of given numbers.
How do you find the lowest common multiple?
To find the lowest common multiple ( LCM ) of any two numbers, multiply the two numbers together and then divide by the greatest common factor (GCF) of the two numbers. 8 and 9 are “relatively prime” they share no common factor other than 1. So the GCF of 8 and 9 is one.
How do you find the most common multiple?
A Common Multiple is a number that is a multiple of two or more numbers. To find the Common Multiples of two or more numbers, follow these steps: Make a list of multiples for each number. Continue your list until at least two multiples are common to all lists.
How to find GCF and LCM?
Prime numbers are numbers that cannot be divided by any other number in mathematics. In this method, you must divide all of the numbers by a prime number such as 2, 3, or any other number. Finally, all of those prime factors will be properly multiplied to find the GCF and LCM .
What is the least common multiple of 54 and 64?
The Least Common Multiple (LCM) of 54 and 64 is the smallest positive number that is a multiple of both 54 and 64. Here we will show you two different ways to figure out the Least Common Multiple of 54 and 64.
