关于其中“两个数的最小公倍数的求法”按教材中有三种常用的方法,宜(1)两数互为质数关系,两数的乘积就是他们的最小公倍数;(2)两数是倍数的关系时,较大数就是他们的最小公倍数;(3)任意两数,他们的最小公倍数可以用短除求法求,只要掌握方法,任何两数都可以快速准确地求出最小公倍数,这种方法教授之后,全班同学几乎百分之百全部能正确求出两数的最小公倍数。
There are three commonly used methods according to the textbook, it is appropriate that (1) the two numbers are mutually prime relations and the product of the two numbers is their least common multiple; (2) The two numbers are Multiples of the relationship, the larger number is their least common multiple; (3) any two, their least common multiple can be used to find the shortest method, as long as the method, any two can quickly and accurately calculate the LCM, which After the method of teaching, the class almost all of the students can find the least common multiple of the two numbers.
