Any multiple of 8 will do, in other words, multiply 8 by any positive integer.
80 and 800 are two.

If you can arrange the counters in the shape of a rectangle with at least two in each row and each column then the number is composite. The numbers of row and the numbers of columns are factors of the given number. If the only rectangle you can make is the "degenerate" one, with only one row or only one column, then the number is prime.
13 and 19 are prime. 33 and 45 are composite.
The squares can have sides equal to each factor that is common to both numbers.
There are four of each.
43 is a prime number because it has exactly two factors, 1 and 43. 33 and 63 each have 3 as a factor as well as 1 and themselves, so they are composite numbers.
identify two composite numbers that each have 8 as a factor
28 and 32

Identify each number as prime, composite or neither: 1
There are infinitely many numbers, and these comprise infinitely many primes and composites. It is not possible to list them all.
In each of those cases, the only composite factor of the number is the number itself.
Prime numbers have one factor pair. Composite numbers have two or more pairs. (6,8) and (4,12) are two different factor pairs for 48.
4 and 9 are two composite numbers that each have only one other factor besides 1 and themselves. The factors of 4 are 1, 2, and 4, and the factors of 9 are 1, 3, and 9.
If you can arrange the counters in the shape of a rectangle with at least two in each row and each column then the number is composite. The numbers of row and the numbers of columns are factors of the given number. If the only rectangle you can make is the "degenerate" one, with only one row or only one column, then the number is prime.
13 and 19 are prime. 33 and 45 are composite.
The relationship between prime numbers and composite numbers is that they are antonyms or opposites of each other. A natural number, is either prime or composite, but it can not be both. Prime numbers have only two factors, one and itself. Composite numbers are whole numbers that are not prime numbers, which means that they have factors other than one and itself.
They are both composite numbers because they each have more than two factors The composite factors of 12 are: 4, 6, 12 The composite factors of 32 are: 4, 8, 16, 32
