I am having trouble finding the LCM betwee these sets of numbers
GRRR!
4, 3, 7
9, 16, 5
5, 4 , 6
9, 11, 2
I have tried several times on these and still am missing something apparently cause I can't get them right!

Just find the lowest number that each will divide into. What I do is take the first number and count out its multiples while looking at the other numbers to see if they are a match.

Least common multiple The first two are just multiple of each other.
If you wanted the LCM between 8 and 6, you break down the factors:
6: 2 * 3
8: 2 * 2 * 2
So you need to have number that has the union of both multiple.
2, 2, 2, 3, or 24. If numbers don't have common factors, there is no LCM lower than just multiplying them all together.
Only the 3rd, has a smaller factor than multiplying all the others.

4, 3, 7 => 84
9, 16, 5 => 720
5, 4, 6 => 60

4, 3, 7 = 84
9, 16, 5 = 720
5, 4, 6 = 60
9, 11, 2 = 198

start by finding the LCM of the two biggest numbers and see if it is a multiple for the smallest one. for example, the lowest common multiple of 7 and 4 is 28, which also happens to be 3 x 8
try to do the others the same way
