最小公倍數 （英語：least common multiple，lcm）是 数论 中的一个概念。 若有一個數 ，可以被另外兩個數 、 整除，且 同時大於或等于 和 ，則 為 和 的 公倍數。 和 的公倍數有無限個，而所有正的公倍數中，最小的公倍數就叫做最小公倍數。 同样地，若干个整数公有的倍数中最小的正整数称为它们的最小公倍数。 整数 的最小公倍数一般记作： ，或者参照英文记法记作 。 对 分數 进行加減运算時，要求兩數的 分母 相同才能計算，故需要通分；标准的计算步骤是将兩個分數的 …

The full form of LCM in Maths is the Least Common Multiple, whereas the full form of HCF is the Highest Common Factor. 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 …

"LCM" stands for "least common multiple". Given two numbers, their LCM is the least (that is, the smallest) common (that is, shared) multiple of those two numbers. For instance, given the two numbers 4 and 5, their LCM is the smallest number that includes each of 4 and 5 as factors; in this example, the LCM is 20. What is the GCF?

2024年1月18日 · The GCF and LCM calculator (also called the GCF finder) will determine the greatest common factor and least common multiple of a set of two to six numbers. You can also compute the GCF and LCM by hand or use the GCF calculator or the LCM calculator to find more detailed methods to compute these problems by hand.

What is the "Least Common Multiple" ? It is simply the smallest of the common multiples. In our previous example, the smallest of the common multiples is 20 ... ... so the Least Common Multiple of 4 and 5 is 20. List the multiples of the numbers until we get our first match. The multiples of 4 are: 4, 8, 12, 16, 20, ...

2024年5月13日 · The lowest common multiple (LCM), or least common multiple, is the smallest number that both numbers divide into exactly. You can Find the LCM of numbers by listing the prime factors of both numbers and then multiply all the prime factors of the larger number by those prime factors of the smaller number that are not already included.

學生在小學階段曾學習以列舉方式找出最大公因數(hcf)和最小公倍數(lcm)。本系列課件先利用圖像方式呈現hcf及lcm的意義，然後示範如何利用短除法來找出兩個數或三個數的hcf和lcm，最後學生可學習如何根據兩數的質因數連乘式求出hcf和lcm。

LCM of two or more numbers is the least number that is exactly divisible by each one of the given numbers. Least Commmon Factor (LCF) can be calculated by any of the following method, Express each one of the numbers as product of prime factors. The product of highest powers of all prime factors gives LCF.
