Prime Numbers

A prime number is a number that has exactly two factors: 1 and itself. All whole numbers greater than 1 are either prime numbers or can be written as the product of prime numbers. There are an infinite number of prime numbers, but they occur less frequently among larger numbers. Prime numbers are important in cryptography and number theory.

Is 2 times 2 times 2 times 3 times 11 times 11 the prime factorization of 264?

23 * 3 * 112 is a prime factorization, but it is the prime factorization of 2904, not 264. The prime factorization of 264 is 23 * 3 * 11. Basically, you had one too many 11's.

Note: If this question is from work you have been assigned by a teacher or professor, I suggest you do the work yourself instead of trying to find the answers online. This will help you to better understand the material and become more familiar with it. Of course, if this question was not from homework, you can disregard this message.

What is the prime factorization of 250 324 72 156 111 128 625 550 405 243 500 512?

2 x 5 x 5 x 5 = 250

2 x 2 x 3 x 3 x 3 x 3 = 324

2 x 2 x 2 x 3 x 3 = 72

2 x 2 x 3 x 13 = 156

3 x 37 = 111

2 x 2 x 2 x 2 x 2 x 2 x 2 = 128

5 x 5 x 5 x 5 = 625

2 x 5 x 5 x 11 = 550

3 x 3 x 3 x 3 x 5 = 405

3 x 3 x 3 x 3 x 3 = 243

2 x 2 x 5 x 5 x 5 = 500

2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 512

What are the prime numbers after 8?

They are infinite but here are the first few after eight: 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 . . .

What two numbers get 366?

There are infinitely many pairs.

Lets us start with addition/subtraction:

183+183, 184+182, 185+181, ... , 365+1, 366+0, 367-1, 368-2, ... and on and on.

Then introduce numbers to 1 decimal place:

183.1+182.9, 183.2+182.8, 183.3+182.7, and so on - forever.

And then two decimal places:

183.01+182.99, 183.02+182.98 and so on.

And then 3 decimal places, 4, and so on to infinitely many decimal places.

Next, look at multiplication/division

1*366, 2*183, 3*122, 4*91.5, and so on

and then start introducing fractions.

What dijit is both even and prime?

None no prime number can be even because it could be divided by 2

Were do you go to get a diagram of the prime factorization of 233357?

233,357 is a prime number. Its only factors are one and itself. Draw it any way you like, unless you mean 2 x 3 x 3 x 3 x 5 x 7. That's the prime factorization of 1890.

How do you find out the prime factor?

To find a prime factorization, divide a composite number and its factors by prime numbers until all the factors are prime. Many people find factor trees helpful in visualizing this process. Example: 210

210 Divide by two.

105,2 Divide by three.

35,3,2 Divide by five.

7,5,3,2 Stop. All the factors are prime.

2 x 3 x 5 x 7 is the prime factorization of 210.

How do you find which is prime and composite number?

if a number is divisible by any other number other than the number itself and 1 , then it is a composite number and if not divisible by any other number other than 1 or the number itself , then it is a prime number . to find it out easyly , take the 1st prime number , that is 2 and eliminate all multiples of 2 from composite number list , then take the next number which is left . i.e. 3 , remove all multiples of 3 and then take the next number left that is 5 and do the same then 7 , then 11 , then 13 , then 17 , then 19 , then 23 , thne 29 , then 31 , then 37 , then 41 , then 47 , then 49 and so on

What is the probability that a number greater that 3 appears while rolling a die?

The answer is 50 percent because if you want to roll higher than three then that is a 4, 5, or 6 or 3 out of 6 numbers.
