Question

find the prime factorisation of 84 by using both division method and factor tree method​

Answer 1

Answer:

2,2,3,7

Step-by-step explanation:

In prime factorization we keep dividing the number (in this case 84) by a prime number until we get to 1.

84/2=42

42/2=21

21/3=7

7/7=1

Factor tree works similarly but in a different layout.

               84

       42               2

   2       21      

           3        7

Hope this helped
