How about: 9, 39, 49, 69, 99 ..... etc which are all composite numbers because they have more than two factors
Yes. Since numbers 9 and 10 are not prime, they are composite. Those numbers that are divisible by some other number are called composite numbers.
4 and 9
Composite numbers are numbers with more than 2 factors. The first composite number is 4. The next composite numbers are 6, 8, and 9. Thus, the fourth composite number is 9.
No, some composite numbers are odd. The smallest composite odd numbers are 9, 15, 21, 25, and 27. Not all even numbers are composite either. There's only one even number that's prime, which is 2.
9, 15, 45 are the composite factors of 45.
The numbers 4, 6, 8, 9, 10, and 12 are composite numbers.
9 is composite as it can be divided by 1, 3 and 9
Yes all are composite numbers.
24, 9, 12, and 2431 are composite numbers. 13 is a prime.
The largest single-digit composite is nine (9).
Square numbers
Well, it's definitely not prime because it's an even number, and all even numbers are divisible by two.(FYI, even numbers are numbers that end in 0,2,4,6, or 8. Odd numbers are numbers that end in 1,3,5,7,or 9)So if it ends in a 4 (which is prime) then it's composite.
