Two ways: Find the square root first. If it's a whole number, find the prime factorization like you would for any other number. Or, find the prime factorization of the original number. The factors will be paired. Take one out of of each pair. Example: 900 The square root of 900 is 30. The prime factorization of 30 is 2 x 3 x 5 or The prime factorization of 900 is 2 x 2 x 3 x 3 x 5 x 5 The square root will be 2 x 3 x 5, or 30
Prime Factorization of 90To find the prime factorization of 90, start with the lowest prime number that will divide into 90. That number is 2. 2 times 45 equals 90. 2 is a number in the prime factorization of 90. Next, find the lowest prime number that will divide into 45. The number is 3, and 3 times15 equals 45. 3 is one of the prime factors, so now you have 2 times 3 times 15. 15 is not a prime number, and the lowest prime number that will divide into 15. 3 times 5 is 15. You'll notice that both 3 and 5 are prime numbers, so the prime factorization of 90 is 2 X 3 X 3 X 5. Check your answer to make sure it is correct and you're done.
The prime factorization of 256 is 28. The square root is 24 or 16.
37 x 37 = 1369 The square root is 37.
No there is not. If you are looking for prime factors of a number and you get to the square root of that number you can stop. Yes, there is. If an integer is not itself a prime, then one of its factors will be less or equal to its square root and the "co-factor" will be greater than or equal to the square root. But both cannot be greater than the square root so, when searching for factors, you can stop when you reach the square root.
99856 = 2*2*2*2*79*79 So sqrt(99856) = 2*2*79 = 316
The square root of 512 is neither an integer, nor even a rational number, so it has no prime factorization.
Since the square root of 18 is not an integer, it doesn't have a prime factorization.
The prime factorization of 10,000 is 24 x 54 The square root is 22 x 52 or 100.
The square root of 11,025 is 105. The prime factorization of 105 is: 3 x 5 x 7
The square root of 729 is 27 and as a product of its prime factors in exponents it is 36
The prime factorization of 36 is 2 x 2 x 3 x 3. The prime factorization of the square root of 36 is 2 x 3, or 6.
3 x 5 = 15
The prime factorization of 1296 is 2^4 x 3^4. That makes the square root 2^2 x 3^2 or 36, -36
As a product of its prime factors: 3*3*7*7 = 441 Its square root is 21 or as 3*7 as the product of its prime factors
