72
Calculate the LCM The least common multiple of 4, 8 and 18 is 72.
What’s the least common multiple of 6 and 18?
631
Since the question is asking for the least common multiple, you factor out the 6 in 18 and 6. This gives you 631 as the LCM because you have factored out 6 and this is the GCF because there are no more common factors between 3 and 1. Since 631 equals 18, 18 is the LCM.
What is the least common multiple of 4 and 6?
12
From the above-given multiples of 4 and 6 is the multiple 12 is the smallest common multiple. Therefore, LCM. of 4 and 6 is 12.

What is the least common multiple LCM of 4/6 and 8?
24
Answer: LCM of 4, 6, and 8 is 24.
What is a common multiple of 4 and 6?
The LCM of 4 and 6 is 12. To find the least common multiple (LCM) of 4 and 6, we need to find the multiples of 4 and 6 (multiples of 4 = 4, 8, 12, 16; multiples of 6 = 6, 12, 18, 24) and choose the smallest multiple that is exactly divisible by 4 and 6, i.e., 12.
What is the least common multiple of 3 and 18?
18
The LCM of 3 and 18 is 18.
What is the LCM of 18 and 3?
What is the LCM of 3 and 18? Answer: LCM of 3 and 18 is 18.
What are the common factors of 4 and 18?
The gcf of 4 and 18 can be obtained like this: The factors of 4 are 4, 2, 1. The factors of 18 are 18, 9, 6, 3, 2, 1. The common factors of 4 and 18 are 2, 1, intersecting the two sets above. In the intersection factors of 4 ∩ factors of 18 the greatest element is 2. Therefore, the greatest common factor of 4 and 18 is 2.
How do you calculate least common multiple?
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
How to figure out LCM?
List all the prime numbers found, as many times as they occur most often for any one given number. Multiply the list of prime factors together to find the LCM . 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.
When do you use LCM?
LCM is also used to add or subtract any two fractions when the denominators of the fractions are different. While performing any arithmetic operations such as addition, subtraction with fractions, LCM is used to make the denominators common.
