Square & Square Root of 123 – Examples, Methods, Calculation
In the domain of mathematics, particularly in algebraic studies, the foundational principles of squares and square roots are of utmost significance. Squaring a number, as demonstrated by multiplying a number by itself, such as 123 squared yielding 15129, is a fundamental operation. It forms a cornerstone in exploring the properties of both rational numbers (expressible as a fraction of two integers) and irrational numbers (which cannot be expressed as a neat fraction). Understanding these basic concepts enhances one’s grasp of mathematical relationships and patterns.

Is the Square Root of 123 Rational or Irrational?
The square root of 123 is an irrational number
The square root of 123 is irrational because it cannot be expressed as a fraction of two integers. It is a non-repeating, non-terminating decimal, demonstrating its irrational nature.
Rational Number:
A rational number is expressible as the quotient or fraction of two integers, with a non-zero denominator. It’s written as a/b, where a and b are integers. Examples include 3/4, -5/2, 0, 1, -2, etc.
Example: Take 3/4; it’s expressed as a fraction, with 3 as the numerator and 4 as the denominator. As both are integers and the denominator isn’t zero, 3/4 is rational.
Irrational Number:
An irrational number is a real number not expressible as a ratio of two integers. Its decimal representation neither terminates nor repeats, and it can’t be written as a/b, where a and b are integers and b isn’t zero. Examples include √2, π, and φ.
Example: For √2, its decimal expansion is approximately 1.41421356…, non-repeating and infinite. Unable to be written as a fraction of two integers, √2 is irrational.
Methods to Find Value of Root 123
To find the value of √123, you can use various methods:
Approximation: Use estimation methods like Newton’s method or approximation techniques to get a close value.
Prime Factorization: Decompose 123 into its prime factors to simplify the root.
Decimal Expansion: Use algorithms like long division or Newton’s method to compute the decimal approximation of √123.
Calculator: Utilize a calculator with a square root function for an accurate numerical value.
Square Root of 123 by Long Division Method
Finding the Square Root of 123 by Long Division Method
Step 1: Preparation
Write 123 as 1 23.00 00 00 and group the digits in pairs. The digit ‘1’ is left alone.
Step 2: Initial Division
Divide the first digit ‘1’ by finding a number × number such that the result is ≤ 1. We get 1 × 1 = 1. The remainder is 0.
Step 3: Bringing Down the Next Pair
Bring down the next pair ’23’ for division. Double the quotient obtained, resulting in 2. The new divisor becomes 20.
Step 4: Iterative Division
Find a number such that (number + 20) × number results ≤ 23. We find (1 + 20) × 1 = 21. Subtract this from 23 to get a remainder of 2.
Step 5: Continuing the Process
Bring down the next pair ’00’. Double the quotient obtained, yielding 22. The new divisor becomes 220.
Step 6: Further Iteration
Find a number such that (number + 220) × number results ≤ 200. We find (0 + 220) × 0. The remainder remains 200.
Step 7: Repeating the Process
Continue the process until reaching the desired level of precision, approximating the square root of 123 to 3 decimal places.
123 is Perfect Square root or Not
No, 123 is not a perfect square number
123 is not a perfect square. A perfect square is a number that can be expressed as the square of an integer. Since 123 cannot be expressed as the product of an integer multiplied by itself, it is not a perfect square.
