Question

find the prime numbers 27,33,34,41,53​

Answer 1

Given,

The given numbers = 27,33,34,41,53

To find,

The prime numbers from the given numbers.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

The prime numbers are only divisible by 1 or the number itself.

Now,

27 is divisible by 3,9,27 and 1

33 is divisible by 3,11,33 and 1

34 is divisible by 2,17,34 and 1

41 is divisible by 41 and 1

53 is divisible by 53 and 1

So, 41 and 53 are only divisible by 1 and by themselves.

(The trick is to find if a number is divisible by atleast one number which is other than 1 and the main number itself. If we find one such divisor then the main number isn't a prime number and if we are unable to find such divisor then the number will be a prime number.)

Hence, 41 and 53 are prime numbers.

Answer 2

Given : numbers 27, 23, 34, 41, 53​

To Find : Identify prime numbers

Solution:

numbers 27, 23, 34, 41, 53​

Prime number are the numbers which have only 2 factors

1 and number itself

27  has factors 1 ,3 , 9 and  27  hence its not a prime number

23 = 1 * 23  hence prime number

34  has factors 1 , 2 , 17 and 34 hence its not a prime number

41 = 1 * 41   hence prime number

53 = 1 * 53  hence prime number

Prime numbers are 23 , 41 and 53
