The sieve of Eratosthenes was discovered in 223 BC.

The Sieve of Eratosthenes filters numbers, letting the composites fall through while the primes remain.

Eratosthenes, a greek philosopher, did, hence the name.

his name isnt sieve but, i know a website all about his life. theres one on eratosthenes on wikipedia. so there, by the way, eratosthenes is the wierdest name ever!!!!!!!!!

About 276 BC

Eratosthenes was a Greek mathematician who is credited with a simple method of making a list of as many primes as you wish. His method is known as the Sieve of Eratosthenes.

The Sieve did not invent prime numbers. It was used to find them.

It was around 200 BC.

Yes and his mother and father were part of the family.

It is called a sieve.

A sieve.

Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.

The mathematical term "sieve of Eratosthenes" is defined as a simple algorithm for finding all prime numbers up to a given limit. It is named after a famous Greek mathematician of the same name.

It was created to help people understand prime numbers

composite numbers

eratosthenes discovered the circumfrance of the world. he was known as the first successful measurement.

The algorithm for identifying prime numbers which is known as the Sieve of Eratosthenes has been accepted as accurate for thousands of years.

Eratosthenes created a sieve that will do that.

the Sieve of Eratosthenes

The word "sieve" in this context is used figuratively with reference to the fact that a sieve does not hold all its contents. Think of sprinkling numbers at the top of the page. The composite numbers get caught, the prime numbers sift on down.

The sieve of Eratosthenes is a simple, ancient algorithm for finding all prime numbers up to any given limit.

prime numbers are invented by srinivasan ramanujan, an Indian mathematician.

To find prime numbers less than 100, the sieve of eratosthenes filters out 1 and all multiples of 2, 3, 5, and 7. All remaining numbers less than 100 are primes.

The sieve of Sundaram sieves out the composite numbers just as sieve of Eratosthenes does, but even numbers are not considered; the work of "crossing out" the multiples of 2 is done by the final double-and-increment step.

One method for finding prime numbers is called the "Sieve of Eratosthenes" because it basically "sifts" through the numbers looking for numbers that are not not prime.

the person that invented the sive was actually eratosthenes of cyrene. cyrene is were he lived which is now in libya, he name the sive after himslef. he was a great mathematician, astronmer, and a excellant geograher, he also worked in a library.

Primes were known to the early Greek Mathematicians - the Pythagoreans about 400BC and Euclid about 300BC. Eratosthenes came up with 'the sieve of Eratosthenes' for working out primes about 200BC. There is no record that the Babylonians knew about primes.

it is a brute force way to find all the primes in a given range. Remove all the composites, and you are left with the primes

The Sieve won't work in that range.

101 103 107 109 113 127 131 137 139 149 151 157 163 167 173 179 181 191 193 197 199

11 is prime; 21 is not. To see whenever a number is prime or not, think if a number can be multiplied by another number to get that number. Or just look at a Sieve of Eratosthenes, if you're not a "thinky" person. :)

Eratosthenes was from ancient greek

Eratosthenes was a Greek scholar of the third century BC born in Cyrene, Roman Greek city near modern day Shahhat in Lybia who went on to become chief librarian at the Library of Alexandria, in Alexandria Egypt (via studying at Athens Greece).

He devised the algorithm in ancient Greece, possibly in either Athens or Alexandria.

Eratosthenes, It says it is Eratosthenes.

Yes, Eratosthenes had two sisters.

The method know as The sieve of Eratosthenes is the easiest method. you simply write down all the numbers from 1 to 100 in rows of 10 and then you go through and you mark out all of the multiples of 2,3,4,5,6,7,8,9,10

Eratosthenes' friend was Archimedes, he also works in Alexandria, Egypt.

You can sift flour using a sieve.

The book Eratosthenes is by Duane W. Roller. This book is written about Geography.

A sieve is a very fine screen used to filter, or sieve, solids out of liquids.

No.

No.

The Sieve of Eratosthenes is one such. Write out the numbers 1 to 100 in 10 rows. Cross out 1. Start at 2 and cross out multiples of 2. That will eliminate all the rest of the even numbers. Go to the next uncrossed-out number (3) and cross out all of its multiples. Some of them will already be crossed out. Proceed in this fashion. Five will be next. You can stop by the time you get to ten. All of the uncrossed-out numbers are prime.

A wet sieve analysis involves using water to wash finer particles through the sieve, while a dry sieve analysis does not involve any added moisture and relies on natural particle movement through the sieve openings. Wet sieve analysis is typically used for cohesive materials, while dry sieve analysis is more commonly used for non-cohesive materials.
