Simplify Square Root of 67140

Here we will show you two methods that you can use to simplify the square root of 67140. In other words, we will show you how to find the square root of 67140 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.

√67140 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 67140 to simplify the square root of 67140. 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 67140. The factors of 67140 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180, 373, 746, 1119, 1492, 1865, 2238, 3357, 3730, 4476, 5595, 6714, 7460, 11190, 13428, 16785, 22380, 33570, and 67140. Furthermore, the greatest perfect square on this list is 36 and the square root of 36 is 6. Therefore, A equals 6.

B = Calculate 67140 divided by the greatest perfect square from the list of all factors of 67140. We determined above that the greatest perfect square from the list of all factors of 67140 is 36. Furthermore, 67140 divided by 36 is 1865, therefore B equals 1865.

Now we have A and B and can get our answer to 67140 in its simplest radical form as follows:

√67140 = A√B

√67140 = 6√1865

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 67140 to simplify the square root of 67140 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 67140 and then take the square root of that product. The prime factors that multiply together to make 67140 are 2 x 2 x 3 x 3 x 5 x 373. 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 67140 by the number (A) squared. 6 squared is 36 and 67140 divided by 36 is 1865. Therefore, B equals 1865.

Once again we have A and B and can get our answer to 67140 in its simplest radical form as follows:

√67140 = A√B

√67140 = 6√1865
