find the square root of 17576 by prime factorization method

Solution

To find the square root of 17,576 using the prime factorization method, we follow these steps:

Step 1: Prime Factorization of 17,576

First, divide 17,576 by the smallest prime number (2 in this case) until it can't be divided by 2 anymore.

17,576÷2=8,78817,576 \div 2 = 8,788 8,788÷2=4,3948,788 \div 2 = 4,394 4,394÷2=2,1974,394 \div 2 = 2,197 Since 2,197 is odd, we try dividing by the next smallest prime number, 3. It's not divisible by 3, so we try 7, 11, 13, 17, 19, and eventually:

2,197÷13=1692,197 \div 13 = 169 Now, 169 can be factored further:

169=13×13169 = 13 \times 13

So, the prime factorization of 17,576 is:

17,576=23×13217,576 = 2^3 \times 13^2

Step 2: Taking the Square Root

To find the square root, we pair the prime factors:

17,576=23×132\sqrt{17,576} = \sqrt{2^3 \times 13^2}

For square root, we take one factor from each pair. From 232^3, we can take one factor of 2 (since one pair is available), and from 13213^2, we take 13.

17,576=2×13=26\sqrt{17,576} = 2 \times 13 = 26

Thus, the square root of 17,576 is 26.
