    1. e.g find the LCM of 12 and 20:
      1. 12
        1. 2
          2. 6
            1. 3
              2. 3
                1. THESE ARE THE PRIME NUMBERS.
            2. 20
              1. 2
                2. 10

                      1. THESE ARE THE PRIME NUMBERS.
                  2. Write the numbers as a product of their prime factors.
                    1. 12=2x2x3
                      1. Start to cross them off in a venn diagram and you will end up with:
                        1. The LCM of 12 and 20 is: 2x2x3x5=60
                      2. 20=2x2x5
