Start by finding the prime factorization of each number, then identify factors shared by all three or by any two of the numbers. Place these factors in a Venn diagram accordingly, with universal factors in the central overlap.

Let's draw a venn diagram of the factors of these numbers.

First let's find the prime factorization of the numbers.

Now identify any factors shared by all, or by some, of the numbers

Now we can draw the venn diagram. Factors that all share are in the middle, and factors shared by 2 numbers are in the overlap between those numbers.
