Square Root of 367

The square root is the inverse of the square of the number. 367 is not a perfect square. The square root of 367 is expressed in both radical and exponential form. In the radical form, it is expressed as √367, whereas (367)^(1/2) in the exponential form. √367 ≈ 19.15724, which is an irrational number because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.

The prime factorization method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers where long-division method and approximation method are used. Let us now learn the following methods:

• Prime factorization method
• Long division method
• Approximation method

The product of prime factors is the prime factorization of a number. Now let us look at how 367 is broken down into its prime factors.

Step 1: Finding the prime factors of 367 Breaking it down, we get 367 itself as it is a prime number.

Step 2: Since 367 is a prime number, it cannot be broken down into smaller prime factors.

Therefore, calculating 367 using prime factorization is not applicable.

The long division method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the square root using the long division method, step by step.

Step 1: To begin with, we need to group the numbers from right to left. In the case of 367, we need to group it as 67 and 3.

Step 2: Now we need to find n whose square is 3. We can say n as ‘1’ because 1 × 1 is lesser than or equal to 3. Now the quotient is 1, and after subtracting 1 × 1, the remainder is 2.

Step 3: Now let us bring down 67, which is the new dividend. Add the old divisor with the same number 1 + 1 to get 2, which will be our new divisor.

Step 4: The new divisor will be the sum of the dividend and quotient. Now we get 2n as the new divisor; we need to find the value of n.

Step 5: The next step is finding 2n × n ≤ 267. Let us consider n as 9, now 2 × 9 × 9 = 243.

Step 6: Subtract 267 from 243, the difference is 24, and the quotient is 19.

Step 7: Since the dividend is less than the divisor, we need to add a decimal point. Adding the decimal point allows us to add two zeroes to the dividend. Now the new dividend is 2400.

Step 8: Now we need to find the new divisor that is 391 because 391 × 6 = 2346.

Step 9: Subtracting 2346 from 2400, we get the result 54.

Step 10: Now the quotient is 19.1.

Step 11: Continue doing these steps until we get two numbers after the decimal point. Suppose if there is no decimal values continue till the remainder is zero.

So the square root of √367 ≈ 19.16.

The approximation method is another method for finding square roots; it is an easy method to find the square root of a given number. Now let us learn how to find the square root of 367 using the approximation method.

Step 1: Now we have to find the closest perfect square of √367. The smallest perfect square less than 367 is 361 (19^2) and the largest perfect square greater than 367 is 400 (20^2). √367 falls somewhere between 19 and 20.

Step 2: Now we need to apply the formula that is

(Given number - smallest perfect square) / (Greater perfect square - smallest perfect square).

Going by the formula (367 - 361) ÷ (400 - 361) = 6 ÷ 39 ≈ 0.154.

Using the formula, we identified the decimal point of our square root.

The next step is adding the value we got initially to the decimal number, which is 19 + 0.154 ≈ 19.154.

So the square root of 367 is approximately 19.154.

• Square root: A square root is the inverse of a square. Example: 4^2 = 16, and the inverse of the square is the square root, that is √16 = 4.
   
• Irrational number: An irrational number is a number that cannot be written in the form of p/q, where q is not equal to zero and p and q are integers.
   
• Principal square root: A number has both positive and negative square roots; however, it is always the positive square root that has more prominence due to its uses in the real world. That is the reason it is also known as the principal square root.
   
• Prime number: A prime number is a number greater than 1 that has no divisors other than 1 and itself.
   
• Long division method: A technique used to find the square root of non-perfect squares by grouping numbers and performing division operations systematically.
