21 and 22 are consecutive composite numbers.
It's any set of consecutive integers that are composite. For instance, 8, 9, and 10 are consecutive composites.
when i did this problem i was doing a eratosthenes sieve method and the numbers was from 1-100 so i got the longest string of consecutive composite numbers on the grid are 74-82 this should be right. BTW I'm 13 doing my moms college work Sorry, but 79 is a prime number. I got 90~96
21 and 22 are the first pair.It can be proven that, given any number n, there are sequences of n consecutive composite numbers.
Basically, composite numbers are the non-prime numbers. Take a table of prime numbers, and look for any two prime numbers, one after the other, that have a difference greater than 2. Any numbers in between are consecutive composite numbers. For example, the next prime number after 13 is 17; that makes 14, 15, and 16 three consecutive non-primes, i.e., composite numbers.
The longest factor string of any composite number is its prime factorization.
A rectangular number is the product of two consecutive integers, that is, n (n + 1). A composite number is a positive integer with more than two factors.
The 13 consecutive numbers from 114 to 126 are composite.The 13 consecutive numbers from 114 to 126 are composite.The 13 consecutive numbers from 114 to 126 are composite.The 13 consecutive numbers from 114 to 126 are composite.
There are no composite numbers between 30 and 31. 30 and 31 are consecutive numbers with no whole numbers between them.
The smallest six consecutive composite integers are:90, 91, 92, 93, 94, 95.(And 96 is also composite, for a run of seven consecutive.)Is that what you were asking ?
114 through 126 are all composite.
For composite numbers, only one string of factors is the longest; the prime factorization.
