The largest integer that is not the product of two or more different primes?
The largest integer that is not the product of two or more different primes would be the largest prime number. Because there are an infinite number of prime numbers, there is no largest integer that is not the product of two or more different primes.
How many twin primes are in 101-200?
301
What is TPI composites?
tracks per inch
How many twin primes are there in 1-100?
101
Write 20 as a product of primes?
20 as a product of primes = 2 * 2 * 5
What is the product of the primes?
The products of the primes are the composites.
What is the ratio of number of primes and composites between 20 and 30?
It is 2:7
What purpose does sieve of Eratosthenes?
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
What numbers 1-100 are composite and prime?
primes are 1,2,3,5,7,11,13,17,19,23,29,31,41,43,47,53,59,61,67,71,73,79,83,89,91. all others are composites.
What is the ratio of prime numbers to composite numbers in this list 2 3 4 5 6 7 8 9 10?
Number of primes = 4 Number of composites = 5 Ratio of primes to composites = 4 : 5
Does Sundaram's Sieve give all primes and composites up to 99?
YES, though i'm not positive.
What is the ratio of the number of primes and the number of composites between and 40?
4 to 15 exclusive 4 to 17 inclusive
What is the ratio of the number of primes and the number of composites between the number of 40?
4 to 15 exclusive 4 to 17 inclusive
What are you filtering with sieve of eratosthenes?
The Sieve of Eratosthenes filters numbers, letting the composites fall through while the primes remain.
Why are prime numbers more useful for the creation of codes than composite numbers?
Actually both are important. Public encryption is based on the product (and so a composite) of two very large prime numbers.
What would be a general rule for composite numbers less 100?
There is no general rule. There is no general rule for primes in any interval and, by extension, there is none for composites.
What is the ratio of the number of primes and the number of composites between 20 and 40?
4 to 15 exclusive 4 to 17 inclusive
