Highest Common Factor
  1. The highest FACTOR that 2 numbers have in common is called the highest common factor (HCF)
    1. e.g find the HCF of 60 and 84:
      1. 60
        1. 2
          1. 30
            1. 2
              1. 15
                1. 3
                  1. THESE ARE PRIME NUMBERS.
                  2. 5
              2. 84
                1. 2
                  1. 42
                    1. 2
                      1. 21
                        1. 3
                          1. 7
                            1. THESE ARE PRIME NUMBERS.
                      2. 60=2x2x3x5
                        1. Now circle the common factors. These are: 2x2x3=12
                          1. The HCF of 60 and 84=12
                        2. 84=2x2x3x7
