There are only 4 different prime numbers less than 9 (2, 3, 5 & 7) and no three of them sum to 9, so the same number must be used more than once eg 2, 2, 5 (20) or 3, 3, 3 (27). If you wrongly regard 1 as a prime then 1, 3 and 5 ie 15 would be an answer.
the two prime numbers will be factors of that number, which would make that number a composite number
There is not such a thing as a composite prime number. A prime number has exactly two factors. A composite number has more than two factors.
Assuming you are referring to the prime factors of the number, the product of the prime factors of any composite number is equal to the number itself.
When a composite number is expressed as a product of its prime factors, the prime factorization of the composite number has been performed.
A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime or composite simply find it's factors. If it has more than two factors than it is not a prime number, it is composite.
Composite. Its prime factors are 23 and 31.
A prime number has only two factors, one and the number itself. A composite number has more than two factors. Factors can be either prime or composite.
A prime number has two factors, a composite number has more than two.
Composite A prime number is a number that has only two factors (itself and one) A composite number is a number that has more than two factors.
ok well i am in prime and composite in math class and this is how: If the number is a prime then it can only have 2 factors. If it has 3 or more it is a composite number. Say 25 has a lot of factors so it is a composite number. And if 1 has only 1 factor then it is a prime number. And there you have prime and composite.
1 and any factors that are themselves composite since none of these are prime.
A prime number has only two factors whereas a composite number has more than two factors
