Oh, dude, the LCM of 12 and 15 using a Venn diagram? That's like trying to use a spoon to eat soup, it just doesn't quite fit. But hey, if you really wanna know, the LCM of 12 and 15 is 60. Just think of it as the magical number where 12 and 15 finally decide to hold hands and skip down the number line together.
To find the GCF and the LCM you have to first at least try to use prime factorization. So use factor trees. Or for the LCM find th least common multiples of the number.
I've never found Venn diagrams all that useful. To draw one successfully, you already have to know the answer. But here goes... Example: 30 and 42 30, 60, 90, 120, 150, 180, 210 42, 84, 126, 168, 210 These are lists of multiples of 30 and 42 respectively, that would be placed in two circles. The number 210 would be placed in the center where they intersect.
The LCM is: 120
The LCM is: 2,520
You can, but there are more efficient ways to find the LCM.
Using a Venn diagram for this problem is overkill, since 6 is a multiple of 3 and will automatically be the LCM of this problem. But if you insist... Put a 3 in the left circle and put a 6 in the space where the two circles intersect.
I can't draw a venn diagram, but this will be close. 2 in the left circle, 24 in the intersection (the gcf), and 3 in the right circle. (2(24)3)=144 which is the LCM.

Venn diagrams are used in a number of different ways and the answer to the question will depend on whether you are looking at finding the LCM or HCF, or looking at conditional probabilities, for example. The question needs to be more specific.
Factor them. 2 x 3 = 6 2 x 2 x 2 x 2 = 16 2 x 19 + 38 Combine the highest amount of each factor. 2 x 2 x 2 x 2 x 3 x 19 = 912, the LCM
Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM

you use the lcm (least common multiple).
We use the LCM to find the least common denominator of unlike fractions.
speed you can just use your brain to find the LCM faster, sometimes.
a and b have no common prime factors. Their LCM is their product.
