Best ResponseYou've already chosen the best response.0isn't that the least common denominator?

Best ResponseYou've already chosen the best response.0It's the least common multiple. To find the LCM, you write out all the factors of each number and pick the factor they have in common that is lowest.

Best ResponseYou've already chosen the best response.0I thought the lcm had to actually be a multiple of both of the numbers

Best ResponseYou've already chosen the best response.0It does. 3 is a multiple of 60 *and* 15, since 3x20 = 60 3x5=15

Best ResponseYou've already chosen the best response.0How i understand it is that the lcm would be the smallest number that both numbers are equal to when multiplied by an integer, such as 15x=0 ,15x1=1, 15x2=30, 15x3=45, 15x4=60 60x0=0, 60x1=60 so they both share 60?

Best ResponseYou've already chosen the best response.0In general: To find the lowest common multiple (LCM) of two or more numbers, list the multiples of the larger number and stop when you find a multiple of the other number. This is the LCM.

Best ResponseYou've already chosen the best response.0Here, check this link out: http://www.mathsteacher.com.au/year7/ch03_prime/03_lcm/lcm.htm It goes through some examples. You'll see what I mean.

Best ResponseYou've already chosen the best response.0According to the link you gave me, the lcm of 6 and 9 is 18...why not 3 like it is for 15 and 60?

Best ResponseYou've already chosen the best response.0Yeah, I'm absolutely sorry  I've been thinking of the wrong thing the whole time. This is what happens when I multitask  I begin to stuff simple things. The LCM of 60 and 15 is 60. You were right.

Best ResponseYou've already chosen the best response.0Yeah I can see that you are answering all of the harder questions that are posted, I just got confused when you said it was three though, but its alright.
