What is LCM and examples?

LCM is the smallest integer which is a multiple of two or more numbers. For example, LCM of 4 and 6 is 12, and LCM of 10 and 15 is 30. As with the greatest common divisors, there are many methods for computing the least common multiples also. One method is to factor both numbers into their primes.

How do you use LCM?

Find the least common multiple (LCM) of two numbers by listing multiples

  1. List the first several multiples of each number.
  2. Look for multiples common to both lists.
  3. Look for the smallest number that is common to both lists.
  4. This number is the LCM.

What is the least common multiple of 4 and 3?

12
Answer: LCM of 3 and 4 is 12.

How do you solve for least common factors?

What is LCM and HCF?

The H.C.F. defines the greatest factor present in between given two or more numbers, whereas L.C.M. defines the least number which is exactly divisible by two or more numbers. H.C.F. is also called the greatest common factor (GCF) and LCM is also called the Least Common Divisor.

What is the least common multiple of 7 and 4?

28
Answer: LCM of 4 and 7 is 28.

How do you calculate the least common multiple?

To find the least common multiple of two numbers, factor the two numbers, noting the frequency of the prime factors, and then multiply the most repeated factors together.

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.

What is the LCM of 6 and 10?

Least common multiple (LCM) of 6 and 10 is 30. LCM(6,10) = 30. Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.

How to find least common multiple?

First,write the numbers,separated by commas

  • Now divide the numbers,with the smallest prime number.
  • If any number is not divisible,then write down that number and proceed further
  • Keep on dividing the row of numbers by prime numbers,unless we get the results as 1 in the complete row
  • Now LCM of the numbers will equal to the product of all the prime numbers we obtained in division method
