Write all prime numbers between 1 to 50.

To find all the prime numbers between 1 and 50, we need to identify the numbers that have only two divisors: 1 and themselves. These are the prime numbers.

Let's go through the numbers from 1 to 50 and check each one:

1 is not prime because it has only one divisor (1). 2 is prime (divisors: 1, 2). 3 is prime (divisors: 1, 3). 4 is not prime (divisors: 1, 2, 4). 5 is prime (divisors: 1, 5). 6 is not prime (divisors: 1, 2, 3, 6). 7 is prime (divisors: 1, 7). 8 is not prime (divisors: 1, 2, 4, 8). 9 is not prime (divisors: 1, 3, 9). 10 is not prime (divisors: 1, 2, 5, 10). 11 is prime (divisors: 1, 11). 12 is not prime (divisors: 1, 2, 3, 4, 6, 12). 13 is prime (divisors: 1, 13). 14 is not prime (divisors: 1, 2, 7, 14). 15 is not prime (divisors: 1, 3, 5, 15). 16 is not prime (divisors: 1, 2, 4, 8, 16). 17 is prime (divisors: 1, 17). 18 is not prime (divisors: 1, 2, 3, 6, 9, 18). 19 is prime (divisors: 1, 19). 20 is not prime (divisors: 1, 2, 4, 5, 10, 20). 21 is not prime (divisors: 1, 3, 7, 21). 22 is not prime (divisors: 1, 2, 11, 22). 23 is prime (divisors: 1, 23). 24 is not prime (divisors: 1, 2, 3, 4, 6, 8, 12, 24). 25 is not prime (divisors: 1, 5, 25). 26 is not prime (divisors: 1, 2, 13, 26). 27 is not prime (divisors: 1, 3, 9, 27). 28 is not prime (divisors: 1, 2, 4, 7, 14, 28). 29 is prime (divisors: 1, 29). 30 is not prime (divisors: 1, 2, 3, 5, 6, 10, 15, 30). 31 is prime (divisors: 1, 31). 32 is not prime (divisors: 1, 2, 4, 8, 16, 32). 33 is not prime (divisors: 1, 3, 11, 33). 34 is not prime (divisors: 1, 2, 17, 34). 35 is not prime (divisors: 1, 5, 7, 35). 36 is not prime (divisors: 1, 2, 3, 4, 6, 9, 12, 18, 36). 37 is prime (divisors: 1, 37). 38 is not prime (divisors: 1, 2, 19, 38). 39 is not prime (divisors: 1, 3, 13, 39). 40 is not prime (divisors: 1, 2, 4, 5, 8, 10, 20, 40). 41 is prime (divisors: 1, 41). 42 is not prime (divisors: 1, 2, 3, 6, 7, 14, 21, 42). 43 is prime (divisors: 1, 43). 44 is not prime (divisors: 1, 2, 4, 11, 22, 44). 45 is not prime (divisors: 1, 3, 5, 9, 15, 45). 46 is not prime (divisors: 1, 2, 23, 46). 47 is prime (divisors: 1, 47). 48 is not prime (divisors: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48). 49 is not prime (divisors: 1, 7, 49). 50 is not prime (divisors: 1, 2, 5, 10, 25, 50).

Now, let's list the prime numbers:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.

These are all the prime numbers between 1 and 50.
