Let's find the lowest common multiple of 4, 6, and 10
🎙️
First, find the prime factorization of each number
🎙️
Now let's make a venn diagram of those factors, with the shared factor, 2, in the center, and the distinct factors in the non-overlapping part of the circle
🎙️
The lowest common multiple comes from the full set of distinct factors, but any shared factors we only count once. So our lowest common multiple is 2 times 2 times 3 times 5, or 60
The skill teaches how to find the lowest common multiple (LCM) of numbers using a Venn diagram. First, determine the prime factorization of each number. Then, create a Venn diagram to visually represent the unique and shared factors. Multiply these factors, shared only once, to find the LCM.
