### What is the Least usual Multiple (LCM)?

In mathematics, the least typical multiple, also known as the lowest typical multiple of 2 (or more) integers a and **b**, is the smallest confident integer the is divisible by both. That is frequently denoted as LCM(a, b).

### Brute pressure Method

There are multiple means to uncover a least common multiple. The most simple is merely using a "brute force" an approach that lists out each integer"s multiples.

EX: | Find LCM(18, 26)18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 23426: 52, 78, 104, 130, 156, 182, 208, 234 |

As have the right to be seen, this an approach can be reasonably tedious, and also is much from ideal.

### Prime factorization Method

A more systematic way to discover the LCM the some given integers is to usage prime factorization. Element factorization involves breaking under each of the numbers being compared into that is product of element numbers. The LCM is then established by multiply the highest power of every prime number together. Note that computing the LCM this way, while much more efficient than utilizing the "brute force" method, is still minimal to smaller sized numbers. Describe the example listed below for clarification on how to use prime administer to recognize the LCM:

EX: | Find LCM(21, 14, 38)21 = 3 × 714 = 2 × 738 = 2 × 19The LCM is therefore:3 × 7 × 2 × 19 = 798 |

### Greatest typical Divisor Method

A 3rd viable technique for recognize the LCM of some offered integers is utilizing the greatest typical divisor. This is also frequently referred to as the greatest usual factor (GCF), amongst other names. Describe the attach for details on just how to determine the greatest usual divisor. Offered LCM(a, b), the procedure because that finding the LCM utilizing GCF is to divide the product that the number a and also **b** by their GCF, i.e. (a × b)/GCF(a,b). Once trying to determine the LCM of much more than 2 numbers, for instance LCM(a, b, c) discover the LCM of **a** and also **b** whereby the an outcome will it is in **q**. Then uncover the LCM of **c** and **q**. The result will be the LCM the all 3 numbers. Using the previous example:

EX: | Find LCM(21, 14, 38)GCF(14, 38) = 2LCM(14, 38) = | 38 × 14 |

2 |

LCM(266, 21) = | 266 × 21 |

7 |

Note that it is not essential which LCM is calculated first as lengthy as every the numbers room used, and the technique is complied with accurately. Depending upon the specific situation, each technique has its own merits, and the user deserve to decide which an approach to pursue at their very own discretion.
