Simplify Square Root of 64620

Here we will show you two methods that you can use to simplify the square root of 64620. In other words, we will show you how to find the square root of 64620 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.

√64620 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 64620 to simplify the square root of 64620. 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 64620. The factors of 64620 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180, 359, 718, 1077, 1436, 1795, 2154, 3231, 3590, 4308, 5385, 6462, 7180, 10770, 12924, 16155, 21540, 32310, and 64620. Furthermore, the greatest perfect square on this list is 36 and the square root of 36 is 6. Therefore, A equals 6.

B = Calculate 64620 divided by the greatest perfect square from the list of all factors of 64620. We determined above that the greatest perfect square from the list of all factors of 64620 is 36. Furthermore, 64620 divided by 36 is 1795, therefore B equals 1795.

Now we have A and B and can get our answer to 64620 in its simplest radical form as follows:

√64620 = A√B

√64620 = 6√1795

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 64620 to simplify the square root of 64620 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 64620 and then take the square root of that product. The prime factors that multiply together to make 64620 are 2 x 2 x 3 x 3 x 5 x 359. When we strip out the pairs only, we get 2 x 2 x 3 x 3 = 36 and the square root of 36 is 6. Therefore, A equals 6.

B = Divide 64620 by the number (A) squared. 6 squared is 36 and 64620 divided by 36 is 1795. Therefore, B equals 1795.

Once again we have A and B and can get our answer to 64620 in its simplest radical form as follows:

√64620 = A√B

√64620 = 6√1795
