Do you need to know all the factors of a number to decide if its prime or composite?

No.
If the number has one factor (other than 1 and itself) it is a composite.
However, to establish that a number is prime it needs to be checked for divisibility by each Prime number up to the square root of the number. If the only factor found is 1, then it is a prime.

How do you decide if a number is prime or composite?
a prime number is if the number only can be divided by 1 and itself. If it has more than 2 factors it is a composite
How do you decide if a counting number is a composite number?
A prime number has exactly two factors, 1 and the number itself. Any number having more factors than a prime is a composite number.
What are the prime factors of a composite prime 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.
Which factors are not included in the prime factorisation of a composite number?
1 and any factors that are themselves composite since none of these are prime.
What do i prime and composite?
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.

What occurs when the composite number is expressed as a number of factors that are all prime?
When a composite number is expressed as a product of its prime factors, the prime factorization of the composite number has been performed.
How do you check if a number is prime or a composite number?
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.
How is a prime number different from the factors?
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.
Is 713 a prime or composite number?

Is 222 prime or composite?
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.

What is the definition of a prime and a composite number and a composite number and a composite number?
A prime number has two factors, a composite number has more than two.
What Is this number prime or composite?
