Let us find the L.C.M. of 2, 3 and 4. The Least Common Multiple (L.C.M.) of two numbers is the lowest number that can be divided both. It can be used to find the lowest common denominator when adding or subtracting fractions. Dont let the "least" in the name fool you - the LCM is no smaller than the largest of the numbers. Find the least common multiple of 7 and 12. Solution: We see that 7 is a prime number and is therefore coprime with any number, which is not divisible by 7. 7 does not divide 12, so 7 and 12 are coprime numbers. Therefore their LCM is their product, 84. Least Common Multiple. Find the LCM of each set of numbers by making a list.11. 5, 6 and 14. 12. 9, 12 and 36. www.MathGeekMama.com.

The process of nding the least common multiple is very useful when adding, subtracting, or comparing unlike fractions (fractions with different denominators). The first number that appears in both lists is 24. (48 appears also, but it is not least), so 24 is the LCM of 6 and 8. Now, can you find the least common multiple of 10 and 35? The least common multiple (LCM) of several whole numbers is the smallest number which is divisible by all these numbers. You have learnt earlier how this is found. The least common multiple of two or more non-zero whole numbers is actually the smallest whole number that is divisible by each of the numbers.Example: Find the least common multiple for 5, 6, and 15. The work below shows how you can use the prime method to calculate the LCM of your numbers. At the bottom you can find a multiplication table ,showing you a different "brute force" way to find the LCM. The Least Common Multiple of the numbers is Least common multiple and greatest common factor. LEAST COMMON MULTIPLE (Most popular as LCM). Lets start this section recalling what are the multiples of a number. Least common multiple of 2 numbers (2-30). Grade 6 Factoring Worksheet. Find the least common multiple (LCM). The lowest, or least, common multiple of 4 and 6 is 12.Take the largest power of each of the prime numbers that appears in either of the original numbers. Because 3 appears only as a multiple of 6, that must be included. The least of the common multiples of two or more numbers is the least common multiple (LCM) .For the crop rotation system described above, the number of years until the farmer grows alfalfa in both fields again is given by the LCM of 6 and 10. 30.
