How do you work out the lowest common factor
WebSo, the common multiples of 4 and 5 are: 20, 40, (and 60, 80, etc ..., too) What is the "Least Common Multiple" ? It is simply the smallest of the common multiples. In our previous example, the smallest of the common multiples is 20..... so the Least Common Multiple of 4 and 5 is 20. Finding the Least Common Multiple WebEarlier we found that the Common Factors of 12 and 30 are 1, 2, 3 and 6, and so the Greatest Common Factor is 6. So the largest number we can divide both 12 and 30 exactly by is 6, like this: The Greatest Common Factor of 12 and 30 is 6.
