It is impossible to list the infinite number of composite odd numbers.
That's an infinite list.
List their factors. Prime numbers have two factors, composite numbers have more than two.
No.
The list of composite numbers is infinite. They all have more than two factors.
The numbers with three or more factors; it's an infinite list.
They are all of the numbers from 1 to 800 that have more than two factors in them.
what is the ratio or prime numbers to composite numbers in this list/10,11,2,13,14,15,16,1,7,18,19,20,21
A composite number is one which has a factor other than 1 and itself.
You do! You first list all the factors of a number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
That's an infinite list. 30 is the first one.
You do! You list the factors to see if it is prime or not. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
