LCM是英文词语,全称为Least Common Multiple,中文意为最小公倍数。这是数学中常用的一个概念,指的是两个或多个整数能够同时整除的最小正整数。在数学中,计算LCM是很常见的,例如求分数的通分、比例的化简等等。
以下是9个含有LCM的例句:
1. The LCM of 12 and 18 is 36.(12和18的最小公倍数是36。)
2. To add or subtract fractions, you need to find the LCM of the denominators.(要做分数的加减法,需要先找到分母的最小公倍数。)
3. The LCM of 3, 5, and 7 is 105.(3、5和7的最小公倍数是105。)
4. In order to compare fractions, you need to find their common denominator, which is the LCM of their denominators.(为了比较分数的大小,需要找到它们的公共分母,即分母的最小公倍数。)
5. The LCM of 6 and 9 is 18.(6和9的最小公倍数是18。)
6. To simplify a ratio, you need to divide both numbers by their LCM.(要化简比例,需要将两个数都除以它们的最小公倍数。)
7. The LCM of 10, 15, and 20 is 60.(10、15和20的最小公倍数是60。)
8. LCM is a useful concept in algebra and number theory.(最小公倍数在代数和数论中都很有用。)
9. To find the LCM of larger numbers, it's helpful to break them down into their prime factors first.(要求较大数的最小公倍数,可以先将其分解质因数。)
