Answer :

Given, a number as 784. We need to find out the square root using prime factorization method.


Step 1: Resolve the given number into prime factors, we get



2 × 2 × 2 × 2 × 7 × 7


Step 2: Make pairs of equal factors, we get


(2 × 2) × (2 × 2) × (7 × 7)


Step 3: Choosing one factor out of every pair, we get


2 × 2 × 7


28


Hence, 28 is the square root of the given number 784 using prime factorization method
