A prime number is a natural number that only has two divisors: itself and 1. In other words, the quotient of the division is a natural number.

Knowing this, let's analize the numbers we were given:

2 is a prime number, since it can only be divided by itself and 1.

21 is not a prime number, since it can be divided by itself, 1, 2, 3 and 7.

8 is not a prime number, since it can be divided by itself, 1, 2 and 4.

29 is a prime number since it can only be divided by itself and 1.

83 is a prime number since it can only be divided by itself and 1.

Finally, 49 is not a prime number since it can be divided by itself, 1 and 7.

In conclusion, the prime numbers from the given list are 2, 29 and 83.
