How to Find the Square Root of 676?
There are different methods to determine the square root of any number. Click here to know more about it. We can determine the square root of 676 using two methods:
 Square Root of 676 by Long Division
 Square Root of 676 by Prime Factorization
Square Root of 676 by Long Division
The square root of 676 can be found using the long division as follows.
 Step 1: We pair digits of a given number starting with a digit at one's place. Put a horizontal bar to indicate pairing.
 Step 2: Now we find a number which on multiplication with itself gives a product less than or equal to 6. As we know 2 × 2 = 4 < 6. Hence, the divisor is 2 and the quotient is 2.
 Step 3: Now, we have to bring down 00 and multiply the quotient by 2. This give us 4. Hence, 4 is the starting digit of the new divisor.
 Step 4: 6 is placed at one's place of new divisor because when 46 is multiplied by 6 we get 276. The obtained answer now is 0. Now the new divisor obtained is 52.
 Step 5: Hence, the square root of 676 is 26.
Square Root of 676 by Prime Factorization
676 is a perfect square hence, we can also express it as (2 × 2 × 13 × 13). The numbers within square root which get repeated are 2 and 13. Hence, the square root of 676 is 2 × 13 = 26 .

Square Root of 676 Solved Examples

Example 1: Can you determine the difference in lengths of square boxes having area 676 square inches and 576 square inches?
Solution
As the area of square box is area = length × length
The length of square box having area 676 square inches is √676 = 26 inches.
Similarly, the length of box having area 576 square inches is √576 = 24 inches.
The difference in lengths of boxes is (26  24) inches = 2 inchesHence, the difference in length of square boxes having area 676 square inches and 576 square inches is 2 inches.

Example 2: Will the radius of circle having area 676π square inches have length of radius less than 30 inches or more than 30 inches?
Solution
Radius can be found using the formula of area of a circle is πr^{2} square inches. By the given information,
πr^{2} = 676π
r^{2} = 676By taking the square root on both sides we get, √r^{2}= √676. We know that the square root of r^{2} is r. By calculating the square root of 676 is 26 inches. Hence, the radius of circle having area 676π square inches will have length of radius less than 30 inches.
