Simplify Square Root of 21663

Here we will show you two methods that you can use to simplify the square root of 21663. In other words, we will show you how to find the square root of 21663 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.

√21663 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 21663 to simplify the square root of 21663. 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 21663. The factors of 21663 are 1, 3, 9, 29, 83, 87, 249, 261, 747, 2407, 7221, and 21663. Furthermore, the greatest perfect square on this list is 9 and the square root of 9 is 3. Therefore, A equals 3.

B = Calculate 21663 divided by the greatest perfect square from the list of all factors of 21663. We determined above that the greatest perfect square from the list of all factors of 21663 is 9. Furthermore, 21663 divided by 9 is 2407, therefore B equals 2407.

Now we have A and B and can get our answer to 21663 in its simplest radical form as follows:

√21663 = A√B

√21663 = 3√2407

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 21663 to simplify the square root of 21663 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 21663 and then take the square root of that product. The prime factors that multiply together to make 21663 are 3 x 3 x 29 x 83. When we strip out the pairs only, we get 3 x 3 = 9 and the square root of 9 is 3. Therefore, A equals 3.

B = Divide 21663 by the number (A) squared. 3 squared is 9 and 21663 divided by 9 is 2407. Therefore, B equals 2407.

Once again we have A and B and can get our answer to 21663 in its simplest radical form as follows:

√21663 = A√B

√21663 = 3√2407
