what number other than one (and the number in question) can you divide by and get a whole number? If the answer is none, then it is a prime number.
Hope this helps!

13 and 17 are both prime because the only two numbers that can go into them which is 1 and itself. So a prime number only has two factors. 2, 3, 5, 7 ,11, and 19 are also prime.

A prime number is a number greater than 1 which is divisible by 1 only like 2,3,5,7,11,13,17, etc.
Hence 13 & 17 are prime numbers.

Because there are no other integers besides 1 and the numbers themselves that you can divide them by and get a whole integer as the answer.

they are called prime because when divided by another integer, they always have a remainder unless the integer is either 1 or the number itself.
