A whole number, which is greater than 1, and which has only 2 factors – 1 and itself, is called a prime numbers. Another way of saying it is that a prime number is defined as a whole number which has only 2 factors – 1 and itself. Some examples of prime numbers are 2,...
Prime numbers are any numbers that cannot be evenly divided by any integer other than 1 and itself. Or in other words, the only numbers that you can multiply to get a prime number are 1 and the prime number. Numbers that are not prime, or those with additional factors other than 1 and...
