最小公倍數 - 维基百科,自由的百科全书
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 X {\displaystyle X} ,可以被另外兩個數 A {\displaystyle A} 、 B {\displaystyle B} 整除 ,且 X {\displaystyle X} 同時大於或等于 A {\displaystyle A} 和 B {\displaystyle B} ,則 X {\displaystyle X} 為 A {\displaystyle A ...
Least common multiple - Wikipedia
In arithmetic and number theory, the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by lcm(a, b), is the smallest positive integer that is divisible by both a and b.
Least Common Multiplier (LCM) Calculator - Symbolab
LCM stands for least common multiple. The least common multiple of integers a and b is the smallest positive number that is divisible by both a and b. To calculate the LCM of two or more numbers, factorize each number into prime factors, write into the exponents form, multiply the factors with the highest powers to get the LCM.
最小公倍数 —— Leatest Common Multiple(LCM) - 知乎 - 知乎专栏
两个数 a 和 b 的最小公倍数 (Leatest Common Multiple) 是指同时被 a 和 b 整除的最小倍数,记为 lcm(a, b) 。 特殊的,当 a 和 b 互素时, lcm(a, b) = ab 。 在 最大公约数 这一节,我们已经学会了求解 gcd 的方法,而求 lcm 需要先求 gcd ,然后容易得到:
研究整除的性质——最大公约数(GCD)和最小公倍数(LCM)_ …
2025年3月14日 · 最大公约数 (Greatest Common Divisor,GCD)指两个或多个整数共有约数中最大的一个。 例如,12 和 18 的公约数是 1、2、3、6,其中最大的是 6,因此 gcd (12, 18) = 6。 整数a和b的最大公约数是能同时整除a和b的最大整数,记为gcd (a,b)。 负整数也可以算GCD,不过由于-a的因子和a的因子相同,在编码时只需要关注正整数的最大公约数。 下面用C++函数std::_gcd (a,b)演示GCD的计算结果,GCD 的结果的符号通常与第一个参数的符号相同。 // 包 …
