Prime Numbers

A prime number is a number that has exactly two factors: 1 and itself. All whole numbers greater than 1 are either prime numbers or can be written as the product of prime numbers. There are an infinite number of prime numbers, but they occur less frequently among larger numbers. Prime numbers are important in cryptography and number theory.

DEFINITELY Composite.

NB ANY EVEN Number, except '2', is composite, there by NOT a PRIME Number.

Is 57 a prime number?

User Avatar

Asked by Wiki User

To be sure, prime numbers are a number which cannot be divisible by every number except for itself and one. Take 5 for an example. There is no possible number which is divisible by itself except for itself and one. So, 5 is a prime number.2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 are all prime numbers to 100. Let's refresh our mind. Now, 57 has factors of 1, 3, 19, and 57. Let's remove the 57 and 1. Now, 3 and 19 are all the factors of 57.
