Question

How to check 117 is prime or not

Answer 1

Answer:

prime numbers are the numbers which don't come in the table of any other numbers or not divisible by other numbers. in the case of 117 it is not a prime number because it is divisible by 3-- 3*39=117 so 117 is a composite number (numbers which are divisible by other numbers). so just to check whether any number is prime or not check it by dividing with other numbers
