Hi

Here we go

52 - can be divided by 2 - therefore NOT Prime

63 - can be divided by 3 - therefore NOT Prime

75 - can be divided by 5 - therefore NOT Prime

31 - cannot be divided by whole numbers - therefore Prime

77 - can be divided by 7 - therefore NOT Prime

59 - cannot be divided by whole numbers - therefore Prime

87 - cannot be divided by whole numbers - therefore*Prime*

Hope this is helpful, if so would you please register that with Fixya

Cheers

Sign into Amazon.com and then mouse-over "Your Account" in the top right of the screen. Click "Your Prime Membership". That will bring up your Prime information. On the left will be a link to "End Membership". Though, if you do order from Amazon a lot, and use their video streaming service, the Prime is definitely worth it. At least to me it is :-)

The common definition is a number only divisible by 1 and itself. This has redundancy for 1, and does not apply.

More formally,**The Fundamental Theorem of Arithmetic**
Every positive integer greater than one can be written *uniquely* as a product of primes, with the prime factors in the product written in order of nondecreasing size.

So 1 is left out.

A prime number is a positive whole number (natural number) which cannot be divided into smaller whole numbers. In short, it can only be divided (integer division) by itself and 1.

First prime number is 2, then 3, 5, 7, 11, 13, 17, 19,

To generate a list of prime numbers the Greek Eratoshenes used a method called now the sieve Eratosthenes.

**all subsequent prime numbers**. If it is not divisible by any prime number, keep going but do not exceed the prime number that is closest yet smaller than square root of your number.

Enjoy.

To generate a list of prime numbers the Greek Eratoshenes used a method called now the sieve Eratosthenes.

- Write all the natural numbers up to some chosen limit (100, 259, any limit )
- Remove 1 by crossing it ( 1 is no longer considered prime).
- The first prime number is 2.
**Circle the number 2.** - Go through the
**whole list**crossing out all the numbers that are multiple of 2, that is 4, 6, 8,10,12, ... - Repeat.
- The next prime number is 3 since it was not crossed out as a multiple of 2.
**Circle 3.** - Go through the
**whole list**crossing all the numbers that are multiples of 3, and which have not already been crossed out as multiples of 2 . - Number 4 has been crossed out already.
- Next prime number is 5.
**Circle 5** - Go through the
**whole list**crossing all the numbers that are multiple of 5 and which have not been crossed out already as multiples of 2, or 3 - Repeat:
- Next prime number is 7.
**Circle 7** **Go through the whole list again, crossing out the multiples of 7, and so on.**

Enjoy.

No not all odd numbers are prime numbers. A prime number is one that cannot be divided equally by any other number then itself or 1. Therefore numbers such as 9 is not a prime number because it can also be evenly divided by 3Hope this answers your question. Thank you.

To prime machine run the hot water cycle, press the button for hot water and open the steam knob until you get a nice flow of water. It is possible that you grind is too fine, try adjusting it coarser by 2 numbers.

hello. now you are making me think about something that i have not thought about in many years.

72 is a composite number because it has factors other than 1 and itself., It is not a prime number.

The 12**factors** of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.

The**factor pairs** of 72 are 1 x 72, 2 x 36, 3 x 24, 4 x 18, 6 x 12, and 8 x 9.

The**proper factors** of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36 or,

if the definition you are using excludes 1, they are 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36. The**prime factors** of 72 are 2, 2, 2, 3, and 3.
