Which number is a common factor of 96 and 72 and the least common multiple of 2 4 and 8 A.8 96.12 C.16 D.24?
The answer is 8.
What is the highest common multiple of B and C?
The greatest common multiple of any set of integers is infinite.
Least common multiple in C programming?
The following code for example is a solution (you could do it with less variables, but this is more readable):int GCD(int a, int b){int n, k, c;n = (a>b)?a:b;k = (a>b)?b:a;while (k){c = n%k;n=k;k=c;}return n;}
How does LCM work?
LCM is the smallest number that can be evenly divided by all the numbers given in the set. For example, LCM(a, b, c, d, e) = f means f is the smallest number such that a, b, c, d, and e all divide f.
Why do some people get confused on LCM and GCF?
Perhaps the C in both means confusion! To eliminate the confusion let's look at some of the reasons for this confusion. Both LCM and GCF have a lot in common. When there are many similarities, it is difficult to see the differences. Both the LCM and GCF are used when studying fractions, a scary topic in and of itself, and both have the word "common" in them when the acronym is read as words. The most confusing part, however, is when looking for the factors, which is a smaller number, we say the word, "greatest" first! When looking for the multiples, which will be a larger number, we say the word, "least" first! I teach my students to say, "Factor, Greatest common factor!" as well as, "Multiple, Least common multiple!" I hope this helped someone! email me: pshaffer@bethsd.org Mrs. Pam Shaffer "Hop2Math"
