Answer 2

Solution :-

We know that,

• Prime numbers are the numbers that have only two factors as one and the number itself .

So, In order to find the rime numbers between 30 and 50 :-

• Remove all even numbers as they are divisible by 2 always .

checking for odd numbers now :-

→ 31 = 1 * 31 => Only 2 factors , so, it is a prime number .

→ 33 = 1 * 3 * 11 => More than 2 factors , so , not a prime number .

→ 35 = 1 * 5 * 7 => More than 2 factors , so , not a prime number .

→ 37 = 1 * 37 => Only 2 factors , so, it is a prime number .

→ 39 = 1 * 3 * 13 => More than 2 factors , so , not a prime number .

→ 41 = 1 * 41 => Only 2 factors , so, it is a prime number .

→ 43 = 1 * 43 => Only 2 factors , so, it is a prime number .

→ 45 = 1 * 3 * 3 * 5 => More than 2 factors , so , not a prime number .

→ 47 = 1 * 47 => Only 2 factors , so, it is a prime number .

→ 49 = 1 * 7 * 7 => More than 2 factors , so , not a prime number .

Hence, the prime numbers between 30 to 50 are 31, 37, 41, 43 and 47 .
