You mean least common multiple right?

TO FIND THE LEAST COMMON FACTOR OF TWO NUMBERS

Step 1) Find the HCF for the two numbers.

For 18 and 30, HCF is 6.

Step 2) Divide that HCF into either number; it doesn't matter which one you choose, so choose the one that's easier to divide.

Choose 18. Divide 18 by 6. Answer = 3.

Step 3) Take that answer and multiply it by the other number.

3 x 30 = 90

Step 4) Celebrate …

… because the answer you just got is the LCM. It's that easy.

Prime factorization.
Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM

I may be the wrong person to answer this, but I've never found a Venn diagram particularly useful in finding an LCM. It's just a way to display the result after you already know what it is. Put the multiples of one number in the left circle, the multiples of the other number in the right circle. Put the first common multiple in the space where they intersect. But you can list the multiples on any piece of paper and don't need the circles. There are much more efficient ways to achieve this.

The least common multiples means the smallest multiple of two numbers so to find a the least common multiple, you find all the multiples, and the smallest in the least common.
