Find the LCM of a set of numbers with this calculator which also shows the steps and how to do the work. Input the numbers you want to find the LCM for.

LCM of 18 and 21 is the smallest number among all common multiples of 18 and The first few multiples of 18 and 21 are 18, 36, 54, 72, 90,. There are 3 commonly used methods to find LCM of 18 and 21 - by division method, by listing multiples, and by prime factorization. The LCM of two non-zero integers , x 18 and y 21 , is the smallest positive integer m that is divisible by both x 18 and y 21 without any remainder. LCM of 18 and 21 can be obtained by multiplying prime factors raised to their respective highest power, i.

Lowest common multiple of 18 and 21

Please provide numbers separated by a comma "," and click the "Calculate" button to find the LCM. 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. There are multiple ways to find a least common multiple. The most basic is simply using a "brute force" method that lists out each integer's multiples. A more systematic way to find the LCM of some given integers is to use prime factorization. Prime factorization involves breaking down each of the numbers being compared into its product of prime numbers. The LCM is then determined by multiplying the highest power of each prime number together. Note that computing the LCM this way, while more efficient than using the "brute force" method, is still limited to smaller numbers. Refer to the example below for clarification on how to use prime factorization to determine the LCM:. A third viable method for finding the LCM of some given integers is using the greatest common divisor. This is also frequently referred to as the greatest common factor GCF , among other names. Refer to the link for details on how to determine the greatest common divisor.

Solved Examples What is the smallest number that is divisible by both 12 and 15? In the Division Method, the given set of numbers are written in the same row separated by a comma.

LCM of 18 and 21 is The Least Common multiple or Lowest common multiple simply known as LCM is the smallest or the least positive integer that is divisible by the given set of numbers. If you consider or or any multiple that is common to 18 and 21, is the first least or smallest number that is common in the set of multiples of 18 and In the Prime Factorisation method, the numbers can be expressed as the product of prime numbers. Here, 18 and 21 can be expressed as;. In the Division Method, the given set of numbers are written in the same row separated by a comma. These numbers are divided with the smallest number that divides all, until no further division is possible or only when prime numbers are left.

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. The LCM of two or more numbers is the smallest number that is evenly divisible by all numbers in the set. Find the LCM of a set of numbers with this calculator which also shows the steps and how to do the work. Input the numbers you want to find the LCM for. You can use commas or spaces to separate your numbers. But do not use commas within your numbers. For example, enter , and not 2,, 1,
