The Least typical Multiple (LCM) is likewise referred to as the Lowest common Multiple (LCM) and also Least typical Divisor (LCD). For 2 integers a and b, denoted LCM(a,b), the LCM is the smallest hopeful integer the is evenly divisible by both a and b. For example, LCM(2,3) = 6 and also LCM(6,10) = 30.

The LCM of two or an ext numbers is the the smallest number that is evenly divisible by every numbers in the set.

You are watching: Least common multiple of 15 and 6

Least typical Multiple Calculator

Find the LCM that a collection of numbers v this calculator which also shows the steps and also how to carry out the work.

Input the number you desire to uncover the LCM for. You have the right to use commas or spaces to different your numbers. However do not usage commas within her numbers. For example, go into 2500, 1000 and not 2,500, 1,000.

How to uncover the Least usual Multiple LCM

This LCM calculator with steps finds the LCM and also shows the job-related using 5 different methods:

How to discover LCM by Listing Multiples

perform the multiples of every number until at the very least one of the multiples appears on every lists discover the smallest number the is on every one of the list This number is the LCM

Example: LCM(6,7,21)

Multiples that 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 Multiples of 7: 7, 14, 21, 28, 35, 42, 56, 63 Multiples the 21: 21, 42, 63 uncover the the smallest number that is on every one of the lists. We have it in bold above. So LCM(6, 7, 21) is 42

How to find LCM by element Factorization

discover all the prime determinants of each given number. List all the element numbers found, as plenty of times together they take place most frequently for any one given number. Multiply the perform of prime factors together to discover the LCM.

The LCM(a,b) is calculate by recognize the prime factorization that both a and b. Usage the same procedure for the LCM of much more than 2 numbers.

For example, for LCM(12,30) we find:

prime factorization that 12 = 2 × 2 × 3 prime factorization that 30 = 2 × 3 × 5 making use of all element numbers discovered as often as each occurs most regularly we take 2 × 2 × 3 × 5 = 60 thus LCM(12,30) = 60.

For example, for LCM(24,300) we find:

prime factorization of 24 = 2 × 2 × 2 × 3 prime factorization the 300 = 2 × 2 × 3 × 5 × 5 utilizing all prime numbers uncovered as often as every occurs most regularly we take it 2 × 2 × 2 × 3 × 5 × 5 = 600 thus LCM(24,300) = 600.

How to uncover LCM by prime Factorization utilizing Exponents

uncover all the prime determinants of each given number and also write them in exponent form. List all the element numbers found, making use of the highest possible exponent discovered for each. Multiply the list of prime determinants with exponents together to find the LCM.

Example: LCM(12,18,30)

Prime factors of 12 = 2 × 2 × 3 = 22 × 31 Prime components of 18 = 2 × 3 × 3 = 21 × 32 Prime determinants of 30 = 2 × 3 × 5 = 21 × 31 × 51 perform all the element numbers found, as numerous times together they happen most often for any type of one offered number and also multiply them together to uncover the LCM 2 × 2 × 3 × 3 × 5 = 180 utilizing exponents instead, multiply with each other each that the prime numbers v the greatest power 22 × 32 × 51 = 180 therefore LCM(12,18,30) = 180

Example: LCM(24,300)

Prime factors of 24 = 2 × 2 × 2 × 3 = 23 × 31 Prime components of 300 = 2 × 2 × 3 × 5 × 5 = 22 × 31 × 52 perform all the element numbers found, as countless times as they occur most often for any one provided number and multiply them with each other to uncover the LCM 2 × 2 × 2 × 3 × 5 × 5 = 600 utilizing exponents instead, multiply with each other each that the element numbers with the greatest power 23 × 31 × 52 = 600 so LCM(24,300) = 600

How to discover LCM using the Cake an approach (Ladder Method)

The cake method uses division to find the LCM that a collection of numbers. Human being use the cake or ladder an approach as the fastest and also easiest way to find the LCM due to the fact that it is simple division.

The cake an approach is the exact same as the ladder method, the box method, the element box method and the grid technique of shortcuts to discover the LCM. The boxes and grids might look a little different, yet they all use department by primes to find LCM.
