Reviewed by Calculator Editorial Team

Simplifying square roots is a fundamental math skill that helps in algebra, geometry, and many other areas of mathematics. This guide explains how to simplify the square root of 636,792 using both manual methods and our calculator.

How to Simplify Square Roots

Simplifying a square root involves expressing it in the form √(a×b) where a is the largest perfect square factor of b. Here's the step-by-step process:

  1. Factor the number under the square root into its prime factors.
  2. Identify pairs of identical prime factors.
  3. Take one factor from each pair out of the square root.
  4. Multiply the factors outside the square root.

Example: Simplify √36

36 = 6 × 6, so √36 = 6.

For larger numbers, this process becomes more complex but follows the same principles.

Simplifying √636,792

Let's simplify √636,792 step by step.

Step 1: Factor the Number

First, we need to factor 636,792 into its prime factors. This is a multi-step process:

  1. Divide by 2 (the smallest prime number): 636,792 ÷ 2 = 318,396
  2. Continue dividing by 2: 318,396 ÷ 2 = 159,198
  3. Continue: 159,198 ÷ 2 = 79,599
  4. Now, 79,599 is not divisible by 2, so we move to the next prime number, 3: 79,599 ÷ 3 = 26,533
  5. Continue dividing by 3: 26,533 ÷ 3 = 8,844.333... (not divisible)
  6. Next prime number is 5: 79,599 ÷ 5 = 15,919.8 (not divisible)
  7. Continue with 7: 79,599 ÷ 7 = 11,371.285... (not divisible)
  8. Continue with 11: 79,599 ÷ 11 = 7,236.272... (not divisible)
  9. Continue with 13: 79,599 ÷ 13 = 6,123 (exact division)
  10. Now, factor 6,123: 6,123 ÷ 3 = 2,041
  11. Factor 2,041: 2,041 ÷ 7 = 291.571... (not divisible)
  12. Next prime is 17: 2,041 ÷ 17 = 120.058... (not divisible)
  13. Next prime is 19: 2,041 ÷ 19 = 107.421... (not divisible)
  14. Next prime is 23: 2,041 ÷ 23 = 89 (exact division)
  15. Now, 89 is a prime number.

Putting it all together, the prime factorization of 636,792 is:

636,792 = 2³ × 3 × 13 × 23 × 89

Step 2: Identify Perfect Square Factors

Looking at the prime factors, we see that 2³ contains a pair of 2s (2²). There are no other pairs of identical prime factors.

Step 3: Simplify the Square Root

We can take one 2 out of the square root:

√636,792 = √(2³ × 3 × 13 × 23 × 89) = 2 × √(2 × 3 × 13 × 23 × 89) = 2√32,538

The simplified form of √636,792 is 2√32,538.

Note: 32,538 is not a perfect square, so this is the simplest radical form.
