            SUB TOPIC: PRIME FACTORISATION(DIVISION 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

            Division Method
            Example 1:
            write the prime factorisation of 36 using division method.






















             Example 2:
            write the prime factorisation of  40 using division mehtod.























             40 = 2 x 2 X 2 x 5
