                           SUBTOPIC: PRIME FACTORISATION (FACTOR TREE METHOD)

            Splitting a given number into its prime factors is known as prime factorisation.
                                                             Or
            Expressing a given number as the product of prime numbers is called as prime factorisation.
              Prime Factorisation can be done in two methods:
            a. Factor Tree Method
            b. Division Method

            Factor Tree Method
            Example 1:
            Write the prime factorisation of 36 by drawing factor tree.
