Answer:
prime numbers are divisible by only 2 numbers: 1 and itself
Explanation:
composite numbers have more factors
2 is the only even prime number
all the other ones are composite
numbers like 55 are not prime.
guess why?
The last digit is 5
which means numbers ending in 5 are divisible by 5
I could go on and on...
Prime numbers have 2 numbers: 1 and that number itself
Composite numbers have more than 2: example; 2 and 31: 2,3,5,7,11,13,19,23,29, and 31.
