Answer 2

for question #1 :
133 = 7 * 19, so 133 is NOT a prime number
143 = 11 * 13, so 143 is NOT a prime number
153 = 9 * 17, so 153 is NOT a prime number
163 = 1 * 163, so 163 is a prime number \(\large \color{red}{\checkmark}\)

basically if a number has no divisors other than 1 and itself, then its a prime number
