Step IV: Take one factor from each pair.

Step V: Find the product of factors obtained in step IV.

Step VI: The product obtained in step V is the required square root.

Square root by prime factorization method

Example 1

Find the square root of 1156.

1156 = 2 x 578

= 2 x 2 x 289

= 2 x 2 x 17 x 17

∴ √1156 = √( 2 x 2 x 17 x 17 )

√1156 = 2 x 17
