What are all the odd composite numbers from 1 to 20?
9 and 15 only.
Are all even numbers composite?
All even numbers are composite except 2 which is a prime numberAll but 2.
What are all the composite numbers from 1000 to 3000?
Composite numbers are positive integers greater than 1 that have factors other than 1 and themselves. To find all the composite numbers between 1000 and 3000, we can start by listing the prime numbers in that range: 1009, 1013, 1019, 1021, 1031, 1033, and so on. Then, we can identify the numbers that are not prime, which are composite. This process would yield a list of composite numbers between 1000 and 3000.
How many odd numbers are between 0 and 1000?
500. Since they alternate, half the numbers between 1 and 1000 are odd and the other half are even. Adding zero to the list does not change the number of odds.
How many composite numbers 1-1000?
Of the 1,000 numbers from 1 to 1,000, 168 are primes and one (the number 1) is neither composite nor prime. Subtracting the 169 numbers that are not composites leaves 831 composuite numbers from 1 to 1,000 (1,000 - 169 = 831).
