Answer :
To determine which of the given numbers is a prime number, we need to understand what a prime number is. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
Let's check each option to see if it is a prime number:
a. 377
The number 377 is not a prime number because it can be divided by 13 and 29, meaning it has divisors other than 1 and itself.
b. 313
The number 313 can only be divided by 1 and 313 without leaving any remainder, indicating that 313 is a prime number.
c. 357
The number 357 can be divided evenly by 3 (since the sum of its digits, 3 + 5 + 7 = 15, is divisible by 3), making 357 not a prime number.
d. 333
The number 333 can also be divided by 3 (since the sum of its digits, 3 + 3 + 3 = 9, is divisible by 3), which means 333 is not a prime number.
Therefore, among the given options, the prime number is b. 313.
