Simplify Square Root of 61605

Here we will show you two methods that you can use to simplify the square root of 61605. In other words, we will show you how to find the square root of 61605 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.

√61605 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 61605 to simplify the square root of 61605. 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 61605. The factors of 61605 are 1, 3, 5, 9, 15, 37, 45, 111, 185, 333, 555, 1369, 1665, 4107, 6845, 12321, 20535, and 61605. Furthermore, the greatest perfect square on this list is 12321 and the square root of 12321 is 111. Therefore, A equals 111.

B = Calculate 61605 divided by the greatest perfect square from the list of all factors of 61605. We determined above that the greatest perfect square from the list of all factors of 61605 is 12321. Furthermore, 61605 divided by 12321 is 5, therefore B equals 5.

Now we have A and B and can get our answer to 61605 in its simplest radical form as follows:

√61605 = A√B

√61605 = 111√5

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 61605 to simplify the square root of 61605 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 61605 and then take the square root of that product. The prime factors that multiply together to make 61605 are 3 x 3 x 5 x 37 x 37. When we strip out the pairs only, we get 3 x 3 x 37 x 37 = 12321 and the square root of 12321 is 111. Therefore, A equals 111.

B = Divide 61605 by the number (A) squared. 111 squared is 12321 and 61605 divided by 12321 is 5. Therefore, B equals 5.

Once again we have A and B and can get our answer to 61605 in its simplest radical form as follows:

√61605 = A√B

√61605 = 111√5
