Meaning math prime number. In mathematics a prime number is any whole number greater than one that has no positive factors other than one and itself. Prime numbers are the positive integers having only two factors 1 and the integer itself. A number that cannot be divided by any other number except itself and the number 1.

A prime number is a whole number greater than 1 whose only factors are 1 and itself. The first few prime numbers are 2 3 5 7 11 13 17 19 23 and 29. For example the number 17 is prime because its only factors are one and 17.

But 1 is not a prime number. Numbers that have more than two factors are called composite numbers. 6 can be made by 2 3 so is not a prime number it is a composite number.

Only 1 5 works but we said to use other whole numbers example. 1 and 3 itself. In total there are 25 of them.

A natural number greater than 1 that is not prime is called a composite number for example 5 is prime because the only ways of writing it as a product 1 5 or 5 1 involve 5 itself however 4 is composite because it is a product 2 2 in which both numbers are smaller. 5 is a prime number. But factors of 7 are only 1 and 7 totally two.

A prime number is a positive integer grater than one that can only be exactly divided by the positie integers 1 and itself without leaving a remainder for example 7 is prime because it can only be divided by 1 and 7. A prime number is the one which has exactly two factors which means it can be divided by only 1 and itself. 3 is a prime number because 3 can be divided by only two number s i e.
