In mathematics, the least common multiple, also known as the lowest common multiple of two (or more) integers a and b, is the smallest positive integer that is divisible by both. It is commonly denoted as LCM (a, b).
How to find LCM of integers?
The LCM is then determined by multiplying the highest power of each prime number together.
Is it important to calculate LCM first?
Note that it is not important which LCM is calculated first as long as all the numbers are used, and the method is followed accurately. Depending on the particular situation, each method has its own merits, and the user can decide which method to pursue at their own discretion.
What is the least common multiple of 4 and 5?
Because 4 and 5 don’t share any factors (4 = 2 times 2 and 5 is prime) the least common multiple is just 4 times 5 = 20.
What is the least multiple of 5?
The least multiple of 5 is 5 itself. If you want it other than 5, then the least multiple of 5 is 10 which is two times 5.
What is the LCM of 4 and 5?
E.g the lcm of 4 and 4 is 4 because to find the answer we can write 4 and 4 =2×2 and 2×2 we will take 2 common frome LHS and also take common from RHS and after that multipl both 2and 2 in this way there is nothing common in 4 and 5 so we will multiply 4 and 5 and get 20 as lcm
What is the largest number in the LCM?
The largest of the original numbers is 12. There are no other multiples of 12 between 12 and 24, and 12 is not divisible by 8, so 24 is the LCM. Check!
How many times does 3 appear in prime factorization?
Also, 3 appears once in the prime factorization of 6, once in the prime factorization of 12, and not at all in the prime factorization of 8. So, the LCM’s prime factorization must have one 3.
What is the maxium multiple of 5?
4 is a even number (2×2) 5 is a prime number so the maxium multiple is 5 ×4 = 20.
How to get multiples of numbers?
A multiple of a number is obtained by multiplying the number by a non-zero whole number (positive integer).
What is the LCM of two or more numbers?
The LCM of two or more numbers is the smallest number that is evenly divisible by all numbers in the set.
How to find LCM of two numbers?
The LCM (a,b) is calculated by finding the prime factorization of both a and b. Use the same process for the LCM of more than 2 numbers.
What is the LCM of a number?
The Least Common Multiple ( LCM) is also referred to as the Lowest Common Multiple ( LCM) and Least Common Divisor ( LCD). For two integers a and b, denoted LCM (a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM (2,3) = 6 and LCM (6,10) = 30.

What is the LCM of 6 and 8?
The LCM of 6 and 8 is 24 because 24 is the smallest number that is both a multiple of 6 and a multiple of 8. This calculator uses the listing multiples method. This method consisits of writing out a list of the lowest multiples of each number, and look for the lowest multiple both numbers have in common. In this example we have: 1 Multiples of 6: 6, 12, 18, 24. Note that 6 = 6 x 1, 12 = 6 x 2, 18 = 6 x 3, 24 = 6 x 4, 30 = 6 x 5 2 Multiples of 8: 8, 16, 24. Also note that 8 = 8 x1, 16 = 8 x 2, 24 = 8 x 3, 32 = 8 x 4, ...
