Simplify Square Root of 17415

Here we will show you two methods that you can use to simplify the square root of 17415. In other words, we will show you how to find the square root of 17415 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.

√17415 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 17415 to simplify the square root of 17415. 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 17415. The factors of 17415 are 1, 3, 5, 9, 15, 27, 43, 45, 81, 129, 135, 215, 387, 405, 645, 1161, 1935, 3483, 5805, and 17415. Furthermore, the greatest perfect square on this list is 81 and the square root of 81 is 9. Therefore, A equals 9.

B = Calculate 17415 divided by the greatest perfect square from the list of all factors of 17415. We determined above that the greatest perfect square from the list of all factors of 17415 is 81. Furthermore, 17415 divided by 81 is 215, therefore B equals 215.

Now we have A and B and can get our answer to 17415 in its simplest radical form as follows:

√17415 = A√B

√17415 = 9√215

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 17415 to simplify the square root of 17415 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 17415 and then take the square root of that product. The prime factors that multiply together to make 17415 are 3 x 3 x 3 x 3 x 5 x 43. When we strip out the pairs only, we get 3 x 3 x 3 x 3 = 81 and the square root of 81 is 9. Therefore, A equals 9.

B = Divide 17415 by the number (A) squared. 9 squared is 81 and 17415 divided by 81 is 215. Therefore, B equals 215.

Once again we have A and B and can get our answer to 17415 in its simplest radical form as follows:

√17415 = A√B

√17415 = 9√215
