What are prime numbers?

Question

What are prime numbers?

Answer 1

a prime nimber is a number that only has two factors 1 and itself.

for example: 2 is a prime number because it's divisble by itself and i but nothing else.

but if you look at 14 that is not a prime number because it is divisble by 1,14,2,and 7.

they call these numbers composite because it is divisble by more than 1 and itself

here is a list of prime number and composite numbers up to 10:

1: (1 is not considered prime or composite)

2: 1,2 Prime

3: 1,3 Prime

4: 1,2,4 Composite

5: 1,5 Prime

6: 1,2,3,6 Composite

7: 1,7 Prime

8: 1,2,4,8 Composite

9: 1,3,9 Composite

10: 1,2,5,10 Composite

Answer 2

Primes are numbers only divisible by 1 and themselves. For a complete list of primes there is an algorithm called the Sieve of Eratosthenes

Answer 3

a positive integer that is not divisible without remainder by any integer except itself and 1, with 1 often excluded: The integers 2, 3, 5, and 7 are prime numbers.  

hope it helped! =]

Answer 4

Prime numbers are those numbers (greater than 1) that cannot be divided by any number except themselves and one.

Answer 5

A prime number is a natural number and greater than 1 that has exactly only two different factors: 1 and itself.

Ex: 2,3,5,7,11 are prime numbers

Answer 6

It is my sincere hope and prayer that you can use the resource for which has been provided for me.

Answer 7

numbers only divisible by themselves and one

e.g 13 is a prime number

14 is not a prime number  because it is divisible by 7 and 2

Answer 8

Numbers with no factors other than itself and one. Like 7 only 1 and 7 can divide into 7

Answer 9

A prime number is has only one and itself as whole number multiples.  For example, 1*5 or 5*1 is equal to five, and that's it, so it's prime.  On the other hand, 1*6 and 6*1 equals six, but so does 2*3 and 3*2, so it isn't prime.  

Answer 10

PRIME NUMBERS are numbers that has only two factors which is 1 and itself
