A Prime number is a number which is only divisable by one and itself,
for example 2,3,5,7,11,13
However it is essential to remember that 2 is the ONLY even prime number and 1 is not a prime number because it is only divisable by itself prime numbers are mostly odd numbers.
I assume you are asking how do you work out the factors of a prime number. A prime number by definition only has itself and 1 as factors.
You is called a prime number!You is called a prime number!You is called a prime number!You is called a prime number!
A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
101 is a prime number. The only factor of 101 is itself and 1.prime
19 is a prime number.19 is a prime number.19 is a prime number.19 is a prime number.

31 is already a prime number.
There is no work. The only prime number ending in 5 is 5.
A prime number is only divisible by itself and 1
The only way to know if a number is prime or not is to try and divide it by every number and if non of them work then it is a prime number
Work out if they have any factors, other than the number 1 and themselves. If they do not they are prime.
You just have to work out it,take each number below it and check whether it is prime or not.
Work it out dumb455
456
17 is a prime number because it has only two factors which are itself and one.
There is no quick way to work out if a number is prime or not, the only way is to see if it can be divided by any numbers that aren't itself or one.
Okay, so a prime number is a number where its only factors are one and itself. (7 cannot be divided by 2,3,4,5, or 6; only by 1 and itself, therefore it is a PRIME number).
