Simplify Square Root of 18515

Here we will show you two methods that you can use to simplify the square root of 18515. In other words, we will show you how to find the square root of 18515 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.

√18515 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 18515 to simplify the square root of 18515. 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 18515. The factors of 18515 are 1, 5, 7, 23, 35, 115, 161, 529, 805, 2645, 3703, and 18515. Furthermore, the greatest perfect square on this list is 529 and the square root of 529 is 23. Therefore, A equals 23.

B = Calculate 18515 divided by the greatest perfect square from the list of all factors of 18515. We determined above that the greatest perfect square from the list of all factors of 18515 is 529. Furthermore, 18515 divided by 529 is 35, therefore B equals 35.

Now we have A and B and can get our answer to 18515 in its simplest radical form as follows:

√18515 = A√B

√18515 = 23√35

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 18515 to simplify the square root of 18515 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 18515 and then take the square root of that product. The prime factors that multiply together to make 18515 are 5 x 7 x 23 x 23. When we strip out the pairs only, we get 23 x 23 = 529 and the square root of 529 is 23. Therefore, A equals 23.

B = Divide 18515 by the number (A) squared. 23 squared is 529 and 18515 divided by 529 is 35. Therefore, B equals 35.

Once again we have A and B and can get our answer to 18515 in its simplest radical form as follows:

√18515 = A√B

√18515 = 23√35
