How many prime numbers are there between 1 and 50?a)18b)12c)15d)20Corr...
Ans.
There is 15 prime no between 1 to 50 always remember 1 is not a prime no because according to prime no definition if given no is divisible by self and 1 that's know as prime no in other words you can say no is divisible by two no’s self and one and now if you go through definition of prime no ,“1” is not satisfied it also you can say “1” is divisible by only one no that's it self so that is why “1”is not a prime no ,so these are all possible prime no between 1 to 50
“2,3,5,7,11,13,17,19,23,29,31,37,41,43,47”

Prime Numbers between 1 and 50:
Prime numbers are numbers greater than 1 that have no divisors other than 1 and themselves. To find the prime numbers between 1 and 50, we need to check the divisibility of each number by all numbers less than itself.
Identifying Prime Numbers:
- Start with the number 2, which is the first prime number.
- Check each number from 2 to 50 for divisibility by numbers other than 1 and itself.
- If a number is only divisible by 1 and itself, then it is a prime number.
Calculating Prime Numbers:
- Prime numbers between 1 and 50 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.
- Counting these prime numbers gives a total of 15 primes between 1 and 50.
Therefore, the correct answer is option 'C' - 15 prime numbers between 1 and 50. These prime numbers play a significant role in mathematics and have various applications in different fields.
