Simplify Square Root of 1257

What is the square root of 1257 in its simplest radical form? 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.

√1257 = A√B

Unfortunately, the square root of 1257 cannot be simplified. Thus, here is the answer to the square root of 1257 in its simplest form:

√ 1257 = √ 1257

Here are two different methods we used to determine why the square root of 1257 cannot be simplified.

1) To be able to simplify the square root of 1257, one of the factors of 1257 other than 1 must be a perfect square. The factors of 1257 are 1, 3, 419, and 1257. Since none of these factors are perfect squares, the square root of 1257 cannot be simplified.

2) To be able to simplify the square root of 1257, all the prime factors of 1257 cannot be unique. When we did prime factorization of 1257, we found that 3 x 419 equals 1257. Since all the prime factors are unique, the square root of 1257 cannot be simplified.
