5
Of those, 5 is not composite.
40, 42, 44, 45, 46
23, 29 and 31 are prime. The rest are composite.
The sum of 5 composite numbers can be either composite, or prime, depending on the case.
I am not sure there is such a classification. It cannot be odd/even Odd numbers: 52 - 22 = 21 Even numbers: 52 - 32 = 16 It cannot be prime/composite Prime: 32 - 22 = 5 Composite: 52 - 22 = 21
0 is a composite number. 5 is prime.
5 is a prime number and is not have a composite number in its factors.
23,465 is composite. All numbers greater than 5 that end in 5 are composite.
2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
5 is a prime number having 1 and 5 as its only factors. It makes no difference to the factors of 5 if the digit 5 is in composite numbers.
All numbers that are greater than 5 and end in 5 are composite numbers because they are divisible by 5 in addition to 1 and the number itself. 655 is therefore a composite number.
605 is composite. (All whole numbers ending in 5 are composite numbers, except the number 5 itself.).
