LCM of 50 and 75 is the smallest number among all common multiples of 50 and 75. The methods to find the LCM of 50, 75 are explained here in detail.
To calculate the LCM of 50 and 70 by thedivisionmethod, we will divide the numbers(50, 70) by their prime factors (preferably common). The product of thesedivisorsgives the LCM of 50 and 70. Step 1:Find the smallest prime number that is a factor of at least one of the numbers, 50...
给你一个n,要求给出两个整数a和b,使得a+b=n且lcm(a,b)最小。 思路 结论:答案是k和n-k,k为n的最大真因子。 证明:假设a<=b,则lcm>=b,取最小则自然是lcm==b,lcm>b,最小的就是2b,2b>n故舍去,所以我们要构造lcm=b的解。 lcm=b故a整除b,则b=ma,所以a+ma=n,故a整除n。现在lcm=b,a是n...
