What is lcm and gcd ?

3,948Member: :

: What is lcm and gcd ?

:

Least Common Multiple - Smallest number that all given numbers can be evenly multiplied into. 2, 3 and 4 = 12 (2*6, 3*4 and 4*3).

Greatest Common Denominator - Largest number that can be evenly divided into all the given numbers. 6, 12 and 15 = 3 (3*2, 3*4 and 3*5).

I could come up with something, but it'd probably be the slowest code anyone has ever seen.

595Member: : : I wrote a program a little while ago that can calculate lcm and gcd of natural numbers. But its slow, to calculate the lcm of 123 345 567, it took 33 seconds. Anybody who can write a code which can perform faster. Thanx in advance.

Ohhh, sorry, I hate that kind of problems, anyways why do you need it ?

PS. You could give your code, maybe there are some opimalizations to do

I am making a program in which I have a compilation of such stuffs, like Mean finder, Base convertor, Prime number detector, Root finder, Exponent finder etc. I am sorry, I can't give you the code. Because, if I do so, my friend would kill me, as he thinks that CODES are more precious than DIAMONDS.

But we are supposed to give up code??? Not a convincing arguement...
