Simplify Square Root of 50421

Here we will show you two methods that you can use to simplify the square root of 50421. In other words, we will show you how to find the square root of 50421 in its simplest radical form using two different methods.

To be more specific, we have created an illustration below showing what we want to calculate. Our goal is to make "A" outside the radical (√) as large as possible, and "B" inside the radical (√) as small as possible.

√50421 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 50421 to simplify the square root of 50421. This is how to calculate A and B using this method:

A = Calculate the square root of the greatest perfect square from the list of all factors of 50421. The factors of 50421 are 1, 3, 7, 21, 49, 147, 343, 1029, 2401, 7203, 16807, and 50421. Furthermore, the greatest perfect square on this list is 2401 and the square root of 2401 is 49. Therefore, A equals 49.

B = Calculate 50421 divided by the greatest perfect square from the list of all factors of 50421. We determined above that the greatest perfect square from the list of all factors of 50421 is 2401. Furthermore, 50421 divided by 2401 is 21, therefore B equals 21.

Now we have A and B and can get our answer to 50421 in its simplest radical form as follows:

√50421 = A√B

√50421 = 49√21

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 50421 to simplify the square root of 50421 to its simplest form possible. This is how to calculate A and B using this method:

A = Multiply all the double prime factors (pairs) of 50421 and then take the square root of that product. The prime factors that multiply together to make 50421 are 3 x 7 x 7 x 7 x 7 x 7. When we strip out the pairs only, we get 7 x 7 x 7 x 7 = 2401 and the square root of 2401 is 49. Therefore, A equals 49.

B = Divide 50421 by the number (A) squared. 49 squared is 2401 and 50421 divided by 2401 is 21. Therefore, B equals 21.

Once again we have A and B and can get our answer to 50421 in its simplest radical form as follows:

√50421 = A√B

√50421 = 49√21
