Simplify Square Root of 81630

Here we will show you two methods that you can use to simplify the square root of 81630. In other words, we will show you how to find the square root of 81630 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.

√81630 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 81630 to simplify the square root of 81630. 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 81630. The factors of 81630 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90, 907, 1814, 2721, 4535, 5442, 8163, 9070, 13605, 16326, 27210, 40815, and 81630. Furthermore, the greatest perfect square on this list is 9 and the square root of 9 is 3. Therefore, A equals 3.

B = Calculate 81630 divided by the greatest perfect square from the list of all factors of 81630. We determined above that the greatest perfect square from the list of all factors of 81630 is 9. Furthermore, 81630 divided by 9 is 9070, therefore B equals 9070.

Now we have A and B and can get our answer to 81630 in its simplest radical form as follows:

√81630 = A√B

√81630 = 3√9070

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 81630 to simplify the square root of 81630 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 81630 and then take the square root of that product. The prime factors that multiply together to make 81630 are 2 x 3 x 3 x 5 x 907. 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 81630 by the number (A) squared. 3 squared is 9 and 81630 divided by 9 is 9070. Therefore, B equals 9070.

Once again we have A and B and can get our answer to 81630 in its simplest radical form as follows:

√81630 = A√B

√81630 = 3√9070
