Simplify Square Root of 28730

Here we will show you two methods that you can use to simplify the square root of 28730. In other words, we will show you how to find the square root of 28730 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.

√28730 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 28730 to simplify the square root of 28730. 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 28730. The factors of 28730 are 1, 2, 5, 10, 13, 17, 26, 34, 65, 85, 130, 169, 170, 221, 338, 442, 845, 1105, 1690, 2210, 2873, 5746, 14365, and 28730. Furthermore, the greatest perfect square on this list is 169 and the square root of 169 is 13. Therefore, A equals 13.

B = Calculate 28730 divided by the greatest perfect square from the list of all factors of 28730. We determined above that the greatest perfect square from the list of all factors of 28730 is 169. Furthermore, 28730 divided by 169 is 170, therefore B equals 170.

Now we have A and B and can get our answer to 28730 in its simplest radical form as follows:

√28730 = A√B

√28730 = 13√170

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 28730 to simplify the square root of 28730 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 28730 and then take the square root of that product. The prime factors that multiply together to make 28730 are 2 x 5 x 13 x 13 x 17. When we strip out the pairs only, we get 13 x 13 = 169 and the square root of 169 is 13. Therefore, A equals 13.

B = Divide 28730 by the number (A) squared. 13 squared is 169 and 28730 divided by 169 is 170. Therefore, B equals 170.

Once again we have A and B and can get our answer to 28730 in its simplest radical form as follows:

√28730 = A√B

√28730 = 13√170
