Is 24 a composite number?
Hello Peacetree, 24 is a composite number as other numbers besides 1 and 24 go into it. For example 2,3, 4, 6, 8 and 12. A prime number, for example 17 has no other numbers that go into it exactly.
How do you find prime numbers?
To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can't be a prime number. If you don't get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).
Which number is prime number?
A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. Numbers that have more than two factors are called composite numbers.

Which is composite number?
A composite number is a natural number or a positive integer which has more than two factors. For example, 15 has factors 1, 3, 5 and 15, hence it is a composite number.
Why is 1 prime or composite?
Using this definition, 1 can be divided by 1 and the number itself, which is also 1, so 1 is a prime number. However, modern mathematicians define a number as prime if it is divided by exactly two numbers. For example: 13 is prime, because it can be divided by exactly two numbers, 1 and 13.

What is a prime number?
An integer greater than one is called a prime number if its only positive divisors (factors) are one and itself. For example, the only divisors of 11 are 1 and 11, so 11 is a prime number, while the number 51 has divisors 3, 17 and 51 itself (51 = 3•17), making 51 not a prime number.
Is zero a prime number?
0 (zero) is not a prime number because it isn't divided by itself. Zero has an infinite number of divisors (any nonzero whole number divides zero). It cannot be written as a product of two factors, neither of which is itself, so zero is also not composite. More concisely, zero is not a prime or a composite number either.

What are Prime Numbers and Composite Numbers?
A prime number is a number which has exactly two factors i.e. ‘1’ and the number itself. A composite number has more than two factors, which means apart from getting divided by 1 and the number itself, it can also be divided by at least one positive integer. 1 is not a prime or composite number.
