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.
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.
That's a bit of unnecessary work. The LCM of 3 and 6 is 6, because 6 is a multiple of 3.
The Least Common Multiple (LCM) for 486 162 300 is 24,300.
42 126 ^ ^ 7x6 14x9 ^ 3x2 ^ ^ 7x2 3x3 7x3x2=LCM is 42
it is fast and easy
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.
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.
You can, but there are more efficient ways to find 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
Look at both of the numbers' prime factors, and put them into a sum. The LCM multiple is the answer you get from that.
To determine the LCM, we'd have to know the value of x. To determine x, we'd have to know the LCM. If x = 1, the LCM is 60. If x = 7, the LCM is 420. If x = 120, the LCM is 120.
The LCM of 4, 7 and 9 is 252. Diagram it however you wish.
Circle A only: 9, 27, 45, 63, 81, 99, 117 Circle B only: No numbers Circle C only: 21, 42, 84, 105 Circles A and B intersect: 18, 36, 54, 72, 90, 108 Circles B and C intersect: No numbers. Circles A and C intersect: 63 Circles A, B and C intersect: 126
Common factors: 3, 5, 15. HCF: 15. To work out: Make a factor tree or ladder. (Ignore the dashes) ----45 ---/---\ --3----15 -------/---\ ------3----5 We cannot go any further as 3 & 5 are prime. Therefore 45 = 3 x 3 x 5. (same with 60) 60 = 2 x 2 x 3 x 5. The easiest way is to now make a venn diagram. Put the numbers that appear in both lists in the intersection. (3 and 5 but do not put both threes in) my venn diagram--->(3)(3, 5) (1, 2) Then, times the numbers in the intersection together... and voila! You get 15 which is the HCF! --To find the LCM, multiply all the numbers in the VENN DIAGRAM together. =] \AT
