Question

Is 11371 is a prime number or not and how can we find it

Answer 1

Hey mate here we go

*A prime number can be divided, without a remainder, only by itself and by 1.

For example, 17 can be divided only by 17 and by 1.

*Some facts*:-

*The only even prime number is 2. All other even numbers can be divided by 2.

*If the sum of a number's digits is a multiple of 3, that number can be divided by 3.

*No prime number greater than 5 ends in a 5. Any number greater than 5 that ends in a 5 can be divided by 5.

*Zero and 1 are not considered prime numbers.

*Except for 0 and 1, a number is either a prime number or a composite number. A composite number is defined as any number, greater than 1, that is not prime.

*To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can't be a prime number. If you don't get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number

Take your question as example

11371 is NOT a Prime number

For example,

11371 can be divided by 83: 11371 / 83 = 137.

To be 11371 a prime number, it would have been required that 11371 has only two divisors, i.e., itself and 1.

After dividing u should get a whole number

then only we can say it is not prime NUM

I hope this will helps you
